Description

Doc no 1000338678 DYNAMIC INTERACTIVE SEAT MAP RELATED APPLICATION [00011 This application is related to International Application Number PCT/US2011/067410 (International Publication Number WO 2012/092287), filed on 27 December 2011, the contents of which are hereby incorporated by reference in their entirety. BACKGROUND [0001A] Computer systems and networks have facilitated the tasks of buying, selling and transferring goods. For example, global computer networks, such as the Internet, have allowed purchasers to relatively quickly and efficiently seek and purchase goods online. Similarly, global computer networks provide an efficient and cost-effective medium for sellers to advertise, offer, provide, and sell their goods. Electronic commerce companies provide buyers and sellers with online services and the infrastructure to accept orders of goods from remote purchasers, to perform the financial transactions necessary to confirm and complete the sale of goods, to ship or distribute the goods to remote purchasers, and to perform other related logistics. For these reasons, sellers actively use the Internet to offer, sell and distribute a wide variety of goods to take advantage of the many benefits provided by the Internet and electronic commerce. [0002] One example of a market for goods within the realm of electronic commerce is the online ticket market. StubHub provides a network-based system which implements an online ticket marketplace for buyers and sellers of tickets for live events such as sports, concerts, theater, and other entertainment events. The StubHub online ticket marketplace enables legitimate, convenient, reliable, and secure transactions at fair market value and provides ticket fulfillment services, even for "sold out" events. Accordingly, the StubHub online ticket marketplace provides benefits for fans who wish to buy, sell or otherwise transfer tickets as well as for teams, artists, and venues. [0002A] Reference to any prior art in the specification is not, and should not be taken as, an acknowledgment or any form of suggestion that this prior art forms part of the common general knowledge in Australia or any other jurisdiction or that this prior art could reasonably be expected to be ascertained, understood and regarded as relevant by a person skilled in the art.

Doc no 1000338678 SUMMARY [00031 Various embodiments relate to systems and methods for providing, at a client computer, an interactive illustration showing where a ticket is located in an event venue. The client computer receives, from a network-based system, a base map illustrating locations of sections within the event venue, a coded image map for building a map overlay having a polygon for each section depicted in the base map, and an inventory for an event at the event venue. The inventory provides, for each section, section data that includes available tickets for each section within the event venue. The client computer displays an interactive seat map by loading the base map and building the map overlay on top of the base map so that each polygon of the map overlay aligns with the respective section of the base map. The client computer determines one or more characteristics for each polygon of the map overlay based on the received section data corresponding to each polygon. The client computer applies the one or more characteristics to each polygon of the map overlay, and links each polygon of the map overlay that includes available tickets to the section in the inventory. [0003A] In one aspect the present invention provides a computer-readable storage medium comprising executable computer program instructions that, when executed, enable a client computer system to: receive, from a network-based system, a base map illustrating locations of sections within the event venue; receive, from the network-based system, a coded image map for building a map overlay comprising a polygon for each section depicted in the base map; receive, from the network-based system, an inventory for an event at the event venue, the inventory providing, for each section, section data that includes available tickets for each section within the event venue; display an interactive seat map by loading the base map and building the map overlay on top of the base map so that each polygon of the map overlay aligns with the respective section of the base map; determine one or more characteristics for each polygon of the map overlay based on the received section data corresponding to each polygon; apply the one or more characteristics to each polygon of the map overlay; and link each polygon of the map overlay that includes available tickets to the section in the inventory. [00041 Implementations can include one or more of the following features. For example the client computer can also display the inventory next to the interactive seat map. The client computer can receive a selection of a polygon of the map overlay, and in response to the selection receipt, display, in the inventory, the section corresponding to the selected polygon. The base map can be a Joint Photographic Experts Group (JPEG) image file 2 )oc no 1000338678 format. The base map can be formed without the use of vector graphics. The base map can be formed using raster graphics. [0005] The client computer can determine the one or more characteristics for each polygon of the map overlay based on the received section data corresponding to each polygon by determining one or more of a color to fill the polygon, a stroke color for the polygon, and a transparency of the polygon. The client computer can link each polygon of the map overlay that includes available tickets to the section in the inventory by displaying the section in the inventory corresponding to the polygon after receiving a selection of the polygon of the map overlay at the client computer. [00061 In another general aspect, a network-based system includes one or more servers to provide a client computer system of a user with a client-side web application configured to communicate with the network-based system and to illustrate at the client computer system where a ticket is located in an event venue. The one or more servers transfer to the client computer system a base map illustrating locations of sections within the event venue; transfer to the client computer system a coded image map for building a map overlay comprising a polygon for each section depicted in the base map; and transfer to the client computer system an inventory for an event at the event venue. The inventory provides, for each section, section data that includes available tickets for each section within the event venue. The one or more servers also receive from the client computer system a selection of one or more available tickets from a selection of a section of an interactive seat map built and displayed at the client computer system using the map overlay and the base map. Other embodiments are described and claimed.

The desktop or mobile widget may comprise, for example, a client-side web application displayed on the desktop or phone-top of one or more of the client devices 104 implemented using various web technologies and programming languages. In various implementations, the desktop or mobile widget may be supported by a host runtime environment such as a web browser or suitable rendering engine and/or may be installed and run as a stand-alone application outside of a web browser. [0033] In various embodiments, the network-based system 110 may provide users with one or more client-side web applications as described in co-pending U.S. Patent Application Serial No. 12/262,468 titled "System and Methods for Providing Location Based Upcoming Event Information Using a Client-Side Web Application Implemented on a Client Device," which was filed on November 31, 2008 and is incorporated by reference in its entirety. In such embodiments, once downloaded and installed on a client device (e.g., PC or mobile device) of the user, the client-side web application may be configured to provide upcoming event information based upon the location of the user. [00341 As shown in FIG. 1, the communications system 100 includes, among other elements, a third party 112 which may comprise or employ a third-party server 114 hosting a third-party application 116. In various implementations, the third-party server 114 and/or third-party application 116 may host a web site associated with or employed by a third party 112 such as an affiliate, partner, or other third-party entity or user in accordance with the 10 )oc no 1000338678 described embodiments. It canbe appreciated that, in some implementations, the third party 112 may provide the third-party application 116 for promoting, enhancing, complementing, supplementing, and/or substituting for one more services provided by the network-based system 110. For example, the third-party server 114 and/or third-party application 116 may enable the network-based system 110 to provide the client 102 with additional services and/or information such as additional ticket inventory. [00351 In some usage scenarios, one or more of the client programs 106 may be used to access the network-based system 110 via the third party 112. For example, the client 102 may use a web client to access and/or receive content from the network-based system 110 after initially communicating with a third-party web site. The web site of the third party 112 (e.g., affiliate, partner) may comprise, for example, a hyperlinked advertisement, a web widget, and/or an API implementation comprising web-based code within a web page to present static or dynamic content hosted by the network-based system 110 and/or to provide programmatic access to the network-based system 110. [00361 It can be appreciated that the hyperlinked advertisement, web widget, and/or API implementation for communicating with the network-based system 110 may be hosted by various third-party web sites such as an affiliate web site, a partner web site, an online marketplace web site, an entertainment web site, a sports web site, a media web site, a search engine web site, a social networking web site, a blog, and/or any other corporate or personal web site or web page in accordance with the described embodiments. In some cases, the third party 112 may be directly or indirectly compensated for directing traffic from the third-party web site to the web site of the network-based system 110 and/or in the event that an electronic commerce transaction results after a user is directed from the third party web sites to the web site of the network-based system 110. [0037] In various embodiments, the web client and/or the network-based system 110 may provide the user with the ability to receive and aggregate content and/or online marketplace and ticket fulfillmrent services of the network-based system 110 and other third-party services (eBay@ services, KijijiTM services, PayPaTM services, etc.). For example, the web client may display location-based upcoming event information that includes event listings published by sellers via the online marketplace services of the network-based system 110 as well as event listings published by sellers via one or more third-party online marketplace services (e.g., eBay@ services, KijijiTM services). In such embodiments, the client-side web application may display an aggregate of ticket inventory 11 )oc no 1000338678 available from multiple online marketplaces providing the user with multiple purchasing options. [00381 The client programs 106 executed by one or more of the client devices 104 may include a programmatic client for accessing and communicating with the network-based system 110. Along with performing a certain set of functions, the programmatic client may include, for example, an implementation of an API provided by the network-based system 110 for enabling access to and/or communication with various elements (e.g., servers, databases) of the network-based system 110. In various embodiments, the API implementation may comprise executable code in accordance with an SDK provided by the network-based system 110. [00391 In some usage scenarios, the programmatic client may be implemented as a standalone or web-based database, point-of-sale (POS), and/or inventory management application for managing a large volume of available inventory and communicating with the network-based system 110. The programmatic client may be employed, for example, by high-volume sellers to author, update, and manage a large number of inventory listings. In some cases, a high-volume seller may use the programmatic client to perform batch-mode communication with the network-based system 110. The batch-mode communication from the high-volume seller may comprise data for numerous inventory items (e.g., hundreds, thousands) for publication by the network-based system 110. The programmatic client also may be used to communicate with the network-based systems in real-time. For example, communications from the high-volume seller may comprise real-time inventory updates so that the listings published by the network-based system 110 accurately reflect the available inventory of the high-volume seller. [00401 The client programs 106 executed by one or more of the client devices 104 (e.g., mobile computing device and/or PC) also may include a messaging client. The messaging client may comprise, for example, an application that supports one or more modes of communication such as e-mail, IM, SMS, MMS, telephone, VoIP, video messaging, and so forth. It can be appreciated that some messaging clients may require and/or launch an Internet connection in the background when executed. [00411 In accordance with various embodiments, the network-based system 110 may communicate with and provide services to users such as buyers and/or sellers of goods such as event tickets. For example, the network-based system 110 may comprise or implement an online ticket marketplace for buyers and sellers of tickets for live events such as sports, 12 )oc no 1000338678 concerts, theater, and other entertainment events. [00421 It is to be appreciated that goods for purchase and/or sale may include both tangible goods (e.g., physical tickets, electronic tickets), intangible goods (e.g., rights and/or licenses that are afforded by the tickets), and other goods in accordance with the described embodiments. It also is to be appreciated that users other than buyers and/or sellers may communicate with the network-based system 110. In some cases, for example, the client 102 may be associated with an administrator or customer service agent and may communicate with the network-based system 110 to monitor, update, and/or otherwise manage one or more computing devices and/or services of the network-based system 110. [0043] FIG. 1 illustrates an exemplary embodiment of the network-based system 110 for providing online ticket marketplace. As shown, the network-based system 110 may comprise or implement a plurality of servers and/or software components that operate to perform various methodologies in accordance with the described embodiments. Exemplary servers may include, for example, stand-alone and enterprise-class servers operating a server OS such as a MICROSOFT@ OS, a UNIX@ OS, a LINUX® OS, or other suitable server-based OS. It can be appreciated that the servers illustrated in FIG. 1 may be deployed in other ways and that the operations performed and/or the services provided by such servers may be combined or separated for a given implementation and may be performed by a greater number or fewer number of servers. [0044] In various implementations, the servers of the network-based system 110 may comprise or implement software components deployed in a tiered environment, where one or more servers are used to host server software running in each tier. For example, using a three-tiered architecture, one or more server software components may be hosted by front end servers, one more server software components may be hosted by a middle tier or middleware implemented by application servers, and one more server software components may be hosted by a back-end tier implemented by databases and/or file systems. In some embodiments, servers of the network-based system 110 may be communicatively coupled with each other via a local area network (LAN) and/or suitable intranet or back-end network. [0045] The network-based system 110 may comprise one or more communications servers 120 for providing suitable interfaces to enable communication using various modes of communication and/or via one or more networks 108. In the embodiment of FIG. 1, the 13 Doc no 1000338678 communications servers 112 include a web server 122, an API server 124, and a messaging server 126 to provide interfaces to one or more application servers 130. The application servers 130 of the network-based system 110 may be structured, arranged, and/or configured to provide various online marketplace and/or ticket fulfillment services to users that access the network-based system 110. [0046] In various usage scenarios, the client 102 may communicate with the applications servers 130 of the network-based system 110 via one or more of a web interface provided by the web server 122, a programmatic interface provided by the API server 124, and a messaging interface provided by the messaging server 126. It can be appreciated that the web server 122, the API server 124, and the messaging server 126 may be structured, arranged, and/or configured to communicate with various types of client devices 104 and/or client programs 106 and may interoperate with each other in some implementations. [00471 The web server 122 may be arranged to host web pages (e.g., HTML documents) and provide an appropriate web interface (e.g., HTTP, CGI, etc.) for enabling data to be presented to and received from entities via the Internet. The web server 122 may be arranged to communicate with web clients and/or applications such as a web browser, web browser toolbar, desktop widget, mobile widget, web-based application, web-based interpreter, virtual machine, and so forth. The web server 122 may provide a web interface to enable access by the client 102 and/or the third party 112 to the various services and functions provided by the application servers 130. For example, the web server 122 may be arranged to receive data from the client 102 and/or third party 112 and to pass the data to one or more application servers 130 within the network-based system 110. The web server 122 also may present the client 102 and/or third party 112 with relevant static and dynamic content hosted by the network-based system 110 in response to various requests and/or events. [00481 The API server 124 may be arranged to communicate with various client programs 106 and/or a third-party application 116 (e.g., third-party web site) comprising an implementation of API for the network-based system 110. The API server 124 may provide a programmatic interface to enable access by the client 102 and/or the third party 112 to the various services and functions -provided by the application servers 130. For example, the programmatic interface provided by the API server 124 may be used for batch-mode and/or realtime communication with a high-volume seller for receiving and updating inventory listings. The programmatic interface provided by the API server 124 also may be used to 14 )oc no 1000338678 communicate relevant static or dynamic content hosted by the network-based system 110 to an API implementation of one or more client programs 106 and/or a third-party application 116 (e.g., third-party web site). The API implementation may comprise, for example, executable code in accordance with a SDK provided by the network-based system 110. [00491 The messaging server 126 may be arranged to communicate with various messaging clients and/or applications such as e-mail, IM, SMS, MMS, telephone, VoIP, video messaging, and so forth. The messaging server 126 may provide a messaging interface to enable access by the client 102 and/or the third party 112 to the various services and functions provided by the application servers 130. For example, the messaging interface provided by the messaging server 126 may be used to communicate with the client 102 and/or the third party 112 in a variety of ways such as via e-mail, IM, SMS, MMS, video messaging, and/or a telephone call (e.g., landline, mobile, VoIP) with a customer service agent and/or IVR system. [00501 When implemented as an online ticket marketplace, the application servers 130 of the network-based system 110 may provide various online marketplace and ticket fulfillment services including, for example, account services, buying services, selling services, listing catalog services, dynamic content management services, delivery services, payment services, and notification services. In the exemplary embodiment shown in FIG. 1, the application servers 130 may comprise an account server 132, a buying server 134, a selling server 136, a listing catalog server 138, a dynamic content management server 140, a payment server 142, a notification server 144, and a delivery server 146 structured and arranged to provide such online marketplace and ticket fulfillment services. [0051] The application servers 130, in turn, may be coupled to and capable of accessing one or more databases 150 including a subscriber database 152, an events database 154, and a transaction database 156. The databases 150 generally may store and maintain various types of information for use by the application servers 130 and may comprise or be implemented by various types of computer storage devices (e.g., servers, memory) and/or database structures (e.g., relational, object-oriented, hierarchical, dimensional, network) in accordance with the described embodiments. Account Services 15 )oc no 1000338678 [00521 The account server 132 implemented by one or more of the application servers 130 may allow a user to establish and/or manage a subscriber account with the network based system 110. For example, while some services provided by the network-based system 110 may be generally accessible, a user may be required to access an existing subscriber account or register a new subscriber account with the network-based system 110 in order to receive certain customized and/or subscriber-specific services. [0053] To create a subscriber account, a user may provide the network-based system 110 with account information such as a unique username, e-mail address, password, name, location (e.g., address, city, country, and/or zip code), telephone numbers (e.g., home, work, and/or mobile), and/or other required information for identifying and/or authenticating the user. After receiving the required account information and instructions from the user to create the subscriber account, the network-based system 110 may create the subscriber account and store the account information in the subscriber database 152. [000541 To effectuate the buying or selling of goods such as event tickets, the user may be required to link the subscriber account of to a source of funds and/or financial value for completing different transactions via the network-based system 110. It can be appreciated that the user may provide various types of entities or third-party financial accounts capable of supplying or receiving funds and/or financial value in accordance with the described embodiments. Exemplary entities and/or third-party financial accounts may include, without limitation, a bank, bank account, lender, line-of-credit, credit card company, credit card account, debit card, prepaid debit card account, third-party payment services account (e.g., PayPalTM account), payroll account, check, money order, or any other suitable source of financial value. [00551 Additionally or alternatively to linking the subscriber account to a source of financial value based on a commercial currency (e.g., U.S. dollar), a user may link to the subscriber account to a source of financial value based on a proprietary and/or promotional currency (e.g., points, rewards, coupons) capable of accumulation and/or redemption by the user to pay for goods or services. It can be appreciated that multiple sources of funds and/or financial value associated with the user may be linked to the subscriber account enabling the user to select among such sources to effectuate different payment transactions via the network-based system 110. The user may select various options for receiving payment when a sale is effectuated via the network-based system 110. For example, the user may request payment for sales via check, deposit to a third-party payment services account (e.g.t PayPalTM account) or Season Ticket Account, and/or other 16 )oc no 1000338678 type of source capable of receiving funds and/or financial value in accordance with the described embodiments. [00561 After a subscriber account is created, the user may view and/or make changes to account information, add or edit existing contacts, retrieve or change the password, view and edit sources of funds and/or financial value on file, view and edit payment options, and/or otherwise manage the subscriber account. In various implementations, the user may customize a subscriber account with one or more interests and ticketing preferences. For example, the user may add and edit information associated with the subscriber account regarding one or more cities, venues, artists, teams and sporting events, theaters, and season ticket and packages of interest to the user. [00571 When accessing the subscriber account, the user may view and/or manage various details of past and pending transactions. For example, the subscriber account may provide a seller with details regarding past and pending ticket sale listings (e.g., shipped, canceled, inactive, expired, deleted, active, pending confirmation, awaiting shipment) and may allow the user to track event listings, modify the prices of event listings, view and confirm received orders, view and confirm orders to ship, print or reprint shipping labels, view shipped orders, view canceled orders, view the status of payments and edit payment options, view past payments, and so forth. The subscriber account also may provide a buyer with details regarding past and pending ticket purchase transactions (e.g., past orders, purchased, delivered, canceled, expired, order status, delivery status, active bids, auctions lost) and may allow the user to view order history, track active bids, modify offers, download and print electronic tickets, view and edit payment options, and so forth. [00581 In accordance with various embodiments, sellers with one or more active listings can access an interactive event venue seat map via their "my active ticket listings" page in their account. A "compare prices" icon may be presented for each active listing that, when clicked, displays an interactive event venue seat map for that listing to allow the seller to keep abreast of pricing trends for the event and make necessary pricing adjustments as needed. [00591 The user also may customize a subscriber account with one or more notification preferences. For example, the user may configure the subscriber account to receive notifications, change notifications, and/or discontinue notifications. In some cases, the user may request to receive promotions via an e-mail newsletter featuring events happening in a particular location. The user also may subscribe to receive customized alert notifications in 17 )oc no 1000338678 a variety of ways such as via e-mail, IM, SMS, MMS, and/or other suitable delivery mechanism. In addition to receiving such notifications via e-mail, IM, SMS, MMS, the user may access the subscriber account and view recent notifications such as alert notifications and other messages received in the past week. [0060] In accordance with various embodiments, sellers with one or more active listings may choose to and/or automatically receive transactional e-mail messages that complement and drive sellers to an interactive event venue seat map. The transactional e-mail messages may inform sellers that their tickets are still listed and that the event date is approaching and also provide a link to the online ticket marketplace and/or an interactive event venue seat map for the event to allow sellers to view the most recent pricing data. Selling Services [0061] The selling server 134 implemented by one or more of the application servers 130 may allow a user to offer goods for sale via an online marketplace provided by the network-based system 110. To list goods for sale such as a single or multiple event tickets, a seller may provide the network-based system 110 with required event information such as event, location of the tickets, sale type, ticket quantity, seating details (e.g., section, row, seat, comments), price, and payment method. It can be appreciated that one or more delivery options may be available for selling the tickets depending on the locations of the buyer and the seller, the time remaining before the event, and/or the form of the tickets (e.g., physical tickets, electronic tickets). [0062] After receiving the required event information and instructions from the seller to publish an event listing, the network-based system 110 may create an active event and store the event information in the events database 154 for publication to users of the network based system 110. The event information stored in the events database 154 may change frequently as new event listings for upcoming events are added and then removed when the tickets for such events listings are purchased. The events database 154 may store relatively static information for an event such as category (e.g., sports, concerts, theater), as well as real-time dynamic information such as current event listings, true levels of ticket inventory, and pricing information for active event listings and sold event listings. [0063] In accordance with various embodiments, the selling server 134 of the network based system 110 may be configured to obtain and/or provide information for active ticket listings and sold ticket listings. The information may comprise pricing information including active ticket prices (e.g., fixed, auction, and/or declining prices for unsold tickets) 18 Doc no 1000338678 and sold ticket prices (e.g., actual prices fans have paid for specific locations) for providing an accurate representation of the current market value of tickets for an event. For each event, the pricing information may comprise data defining active listings (e.g., section, row, quantity, listed price) and sold listings (e.g., section, row, quantity, date, sold price) for each section and for each zone (e.g., aggregated sections) in an event venue. [00641 The pricing information also may include data defining the highest price, the lowest price, and the average price for all active tickets and/or sold tickets within any section or zone. In some implementations, the average price may be calculated as a median price for all active and/or sold tickets within any section or zone by dropping the lowest and highest priced tickets. The pricing information may comprise data defining comparable sections, such as the top ten sections which are closest in price. The pricing information may further comprise the overall average ticket price for an event calculated, for example, by dropping the five lowest and highest priced tickets. The pricing information also may include rising and falling pricing trend information such as price change data (e.g., the percentage change in the average price of sold tickets for an event within the last N number of days), listing rate data (e.g., the percentage change in the amount of active listings within the past week, and/or selling rate data (e.g., the percentage change in the amount of sold tickets within the past week). It can be appreciated that other types of information and/or data may be obtained and/or provided in accordance with the described embodiments. 100651 To create an event listing for publishing tickets for an upcoming event which are for sale, a seller may select the appropriate type of event, city, or venue for event tickets being offered for sale, and then may be queried or prompted to select a specific event after making selections from various categories and subcategories presented via a set of interactive pull-down menus. Once an event has been selected, the seller may provide the price per ticket and the ending date of the sale when the event listing is to be removed from publication. For some events, the event listing may expire three business days before the event. In certain markets, tickets may be sold on consignment and the listing may remain until the start of the event. [00661 In some cases, if the seller has additional tickets to list for the same event or for the same team (e.g., season tickets), the seller is able to start the listing process for the additional tickets with the previously selected ticket event (e.g., Mar. 20, 2007 Dallas Mavericks @ New York Knicks), the previously selected genres (e.g., sports, basketball, 19 )oc no 1000338678 NBA, 2006-20007 regular season, New York Knicks), and/or the previously selected seats. For example, the seller may list multiple tickets as described in co-pending U.S. Patent Application Serial No. 11/689,787 titled "System and Method for Posting Multiple Items for Sale," which was filed on March 22, 2007 and is incorporated by reference in its entirety. [00671 In accordance with various embodiments, the seller creates an event listing for publishing tickets to an upcoming event which are for sale. To create the event listing, the seller may be presented with a pull-down menu listing categories such as sports tickets, concert tickets, theater and arts tickets, and ticket gift certificates. If the seller selects the sports tickets category, a pull-down menu listing sports tickets such as baseball tickets, basketball tickets, football tickets, and other types of sports tickets is presented. If the seller then selects football tickets, a pull-down menu listing sports subcategories such as NFL tickets, CFL tickets, and NCAA tickets is presented. If the seller selects the NFL tickets, a pull-down menu listing ticket subcategories such as NFL regular season tickets, NFL playoff tickets, and NFL pro bowl tickets is presented. If the seller selects the NFL regular season tickets, a pull-down menu listing NFL teams is presented. Once the seller selects tickets for particular NFL team, a listing of available events including event details (e.g., team and opponent, date, time, venue name) for the team are displayed which can be sorted by event, date, and venue. The seller may then select an event from the listing of available events. It can be appreciated that appropriate sets of pull-down menus for listing categories and successive subcategories may be presented for any type of event ticket in accordance with the described embodiments. [0068] After an event has been selected, the seller may provide the network-based system 110 with the shipping location of the tickets and verify current contact information (e.g., address and telephone phone number). The seller may select from various delivery options (e.g., courier, electronic delivery) and provide a sale type such as a fixed price sale (e.g., set price capable of subsequent modification), a declining price sale (e.g., automatically decreasing price over time from maximum price to minimum), or an auction sale (e.g., buyers bid from a starting price during an open period with the highest bidder placing an order when the auction closes). [0069] The seller may provide the ticket quantity for specific seats or general admission. The seller may provide the ticket quantity and may allow the quantity of offered tickets to be split among several buyers in multiples of two. The seller may provide seating and ticket 20 Doc no 1000338678 details for the offered tickets such as section, row, seat numbers, and may provide other comments. In some cases, the seller may select to prevent buyers from viewing the specific seat numbers when the event listing is published by the network-based system 110. [0070] In accordance with various embodiments, when entering seating and ticket details, the seller may be presented with a user interface that provides a "lookahead" section filter. As the seller begins to type partial information for an event that is associated with an interactive event venue seat map into a "section" field, the field is read, and relevant sections are displayed to the seller in a drop down menu. The seller may then choose the section from the menu making the entering of ticket details easier for the seller and reducing the number of listings that go unmapped and therefore unsold. [0071] After the seller has provided the required seating and ticket details, the seller is prompted to enter a price per ticket and payment method. The seller may provide a selected payment method for the sale of the tickets such as via check, deposit to a third-party payment services account (e.g., PayPalTM account), Season Ticket Account, and/or other type of source capable of receiving funds and/or financial value. The seller also may select to donate some or all of the proceeds of a sale to a third-party such as a non-profit organization or entity (e.g., charity, foundation, fund, alliance, society) as described in co pending U.S. Patent Application Serial No. 10/697,850 titled "System and Method for Providing Logistics for a Sale or Transfer of Goods with Proceeds Provided to a Third Party," which was filed on October 30, 2003 and is incorporated by reference in its entirety. [00721 In accordance with various embodiments, the listing process for sellers includes a price mapping feature that introduces sold ticket data in a uniformly displayed interactive event venue seat map for enabling sellers to view both sold and current listing data for any section or zone in an event venue. When entering pricing information, the seller may be presented with a user interface for entering payment method and pricing information that provides a "compare prices" feature. In addition to providing a "price" field for allowing the seller to enter a price per ticket, the user interface may provide a "compare prices" icon. When the "compare prices" icon is clicked, the seller is presented with an interactive event venue seat map regardless of whether the seller has entered pricing information. [00731 In one or more implementations, the interactive event venue seat map may be displayed within a DIV pop-up overlay that substantially overlays (e.g., 70% overlay) the user interface for entering the payment method and pricing information. The overlay may provide the event information (e.g., event name, venue, and date), ticket details (e.g., section 21 )oc no 1000338678 and row entered by the seller), pricing trend information (e.g., rising or falling sales), and an event summary (e.g., average price for the event, number of active listings, and number of sold listings). The overlay also may include a "price input" field for entering and/or editing a price per ticket. In some cases, the "price input" field may be pre-populated with previously entered pricing information. When pricing information (e.g., price per ticket) is included in the "price input" field, the overlay may provide a ticket price comparison showing the total number of comparable sections. [00741 In accordance with various embodiments, the overlay comprises an interactive event venue seat map comprising a layout of the event venue indicating sections of the event venue for which tickets are listed. In response to the ticket details (e.g., section and row entered by the seller), a tabbed sold/active pop-up window is displayed that overlays a portion of the interactive event venue seat map that presents the name of the section entered by the seller and available pricing information for the section and corresponding tab (e.g., sold tab or active tab). In one implementation, the sold/active pop-up window presents the lowest (sold/active) price for the section, the average (sold/active) price for the section, the highest (sold/active) price for the section, and corresponding indicators. When pricing information is available for the section of the seller, a section marker pointing to the section and indicating the average price for the section is also presented on the interactive event venue seat map. If there is no available pricing information for the section of the seller, a message is displayed requesting the seller to click on a comparable section. [0075] When pricing information is available for the section, the sold/active pop-up window also presents ticket details and transaction information for sold or active event listings that may be displayed in columns that can be sorted by the seller. The ticket details for sold event listings may include row and quantity, and the transaction information for sold event listings may include the sold date and price paid. The ticket details for active event listings may include row, and quantity, and the transaction information for active event listings may include the listed price per ticket. [00761 In response to the price per ticket entered by the seller, section markers pointing to comparable sections that are within a predetermined range of the price per ticker entered by the seller and indicating the average price for tickets within each comparable section are presented on the interactive event venue seat map. Such section makers show sections where the average sold price is close to the price that the seller is considering which helps the seller pinpoint sections to look at in more detail. 22 )oc no 1000338678 [0077] The interactive event venue seat map allows the seller to browse and click on sections to see sold and listed data for any section in the event venue. When presented with the interactive event venue seat map, the seller may roll over a particular section causing a roll-over screen to appear that includes the section name, the average sold price for tickets in the section, and the average listed price for tickets in the section. If the particular section is clicked and pricing information is available for the zone, the sold/active pop-up displays the section name and presents ticket details and transaction information for sold or active event listings within the section. [0078] The interactive event venue seat map also provides a zone view that allows sellers to click on any zone name in a zone legend to see all sold and listed data for that zone. If a zone name is clicked and pricing information is available for the zone, the sold/active pop-up displays the zone name and presents ticket details and transaction information for sold or active event listings within the zone. If the sold tab is selected, the ticket details include section, row, and quantity, and the transaction information includes the sold date and price paid. If-the active tab is selected, the ticket details include section, row and quantity, and the transaction information includes the listed price per ticket. When the seller clicks a different tab, pricing information, ticket details, and transaction information corresponding to the different tab is presented if available. [0079] The interactive event venue seat map also provides a "compare feature" to provide sellers with a quick visual indication whether a proposed sale price is within a sale price range determined from sold and current listing data of other similar listings. For example, the seller may enter or edit and price per and use the compare feature to view a list of comparable sections and available pricing information. After being presented with market value information and finally deciding on a price per ticket, the seller can save and/or update the price of a ticket for a new or existing event listing. [0080] In general, the interactive event venue seat map provides sellers with the opportunity to view pricing details to allow for a more accurate picture of the current market value of their tickets. Accordingly, sellers are better able to price their tickets based on the truest market value, resulting in a quicker sale. In some embodiments, the interactive event venue seat map also may provide a visual warning to a seller when a proposed price is not competitive with respect to sold and current listing data of other similar listings. Buying Services [00811 The buying server 136 implemented by one or more of the application servers 23 )oc no 1000338678 130 may allow a user to locate goods offered for sale via an online marketplace provided by the network-based system 110. To find goods for sale such as a single or multiple event tickets, a buyer may view active event listing published by the network-based system 110. [0082] In accordance with various embodiments, information may be presented to and/or received from information from the user via one or more user interfaces presented on the display of a client device (e.g., PC or mobile device). The user interfaces presented to the user by a client-side web application may comprise a search engine interface (e.g., text entry boxes, input fields, checkboxes, clickable hyperlinks, pull-down menus, etc.) for allowing the user to provide event criteria for searching and/or filtering event listings. The user interfaces presented to the user also may comprise search results including upcoming event listings that satisfy the event criteria. [0083] For example, the buyer may browse active event listings by clicking and following links for various event categories and subcategories such as sports tickets, concert tickets, theater tickets, cities, sports, teams, artists, show type (e.g., Broadway, opera, ballet, comedy), event names, and so forth. The buyer also may search for events using a search engine interface and/or one or more pull-down menus. For example, the buyer may enter one or more keywords into a search engine text entry box and view results comprising active events that satisfy the query. In various implementations, the buyer may be presented with a ticket finder screen comprising a plurality of pull-down menus for allowing the buyer to quickly formulate a search by selecting a category (e.g., sports, concert, theater, etc.), a location (e.g., city), and a number of tickets from the pull-down menus. [0084] In some embodiments, a user may search for and/or request upcoming event information based on a variety of event criteria such as an event name, category, city, venue, artist, genre, team, player (e.g., starting pitcher, favorite player), theater, date range, date, number of tickets, price range, ticket attributes (e.g., zone range, zone, section range, section, row range, row, seat number range, seat number), and/or combination thereof. Accordingly, the event criteria included in a search query may comprise ticket attributes as well as one or more conditions associated with the event parameters for requesting information for such upcoming events only when such conditions are met. [00851 It can be appreciated that various combinations of event criteria are possible in accordance with the described embodiments. For example, a user may request upcoming event information specifying combinations such as a certain number of tickets and a 24 )oc no 1000338678 maximum price, a particular artist and a certain city, a certain player and a particular event venue, and so forth. A user also may request upcoming event information based on one or more ticket attributes. For instance, a user may request a certain number of tickets for an upcoming event in one or more specified zones, sections, rows, and/or or seats. Additionally, event criteria may be applied alone or in combination across one or more events. A user may request, for example, tickets in a certain row (e.g., front row) or row range (e.g., rows 1-5) within a specified zone (e.g., club infield) or section (e.g., section 224) for a designated team (e.g., professional baseball team) and/or for one or more games (e.g., particular opponent, rivalry game). The embodiments are not limited in the regard. [0086] It can be appreciated that in some cases, an upcoming event may not satisfy all event criteria specified by the user. For example, tickets for an upcoming event may be available but not within a price range specified by the user. Additionally, there may be no upcoming events that satisfy the event criteria specified by the user when there are no available tickets such as when no sellers have listed tickets for an event and/or before tickets for an event go on sale. In such cases, the client-side web application may inform the user that there are no search results satisfying the search criteria and then perform a new search with relaxed search criteria. Alternatively or additionally, the client-side web application may automatically relax the search criteria and attempt another search. [0087] Once a buyer has located and selected an event, the tickets being offered for sale for the event may be presented to the buyer. In various embodiments, the user may view the details of tickets being offered for sale and the location of tickets in the event venue as described in co-pending U.S. Patent Application Serial No. 11/552,782 titled "Method and System for Illustrating Where a Ticket is Located in an Event Venue," which was filed on October 25, 2006 and is incorporated by reference in its entirety. In such embodiments, the buyer may be presented with an interactive event venue seat map and details of available tickets according to criteria specified by the buyer. [0088] In one implementation, for example, after selecting an event the buyer may be presented with an interactive event venue seat map and an initial listing of all event tickets for sale. The event listings may include details such as section, row, quantity, and price and may be sorted by the buyer according to such details. The sections of the interactive event venue seat map for which tickets are available may be displayed in color while sections having no available tickets may be displayed in white. [0089] Within the interactive event venue seat map, comparable or similarly-located 25 oc no 1000338678 (e.g., upper level) sections having available tickets may be displayed in the same color while sections having available tickets that are not comparable or similarly-located may be displayed in different colors. For example, the colors used in the sections may correspond to zones for the sections with each zone comprising several comparable or similarly located sections. Along with the interactive event venue seat map, the buyer may be presented list comprising the different zone names and the color used for each zone. The names of zones having available tickets may be displayed in black text, while the names of zones having no available tickets may be displayed in gray text. [00901 When presented with the interactive event venue seat map, the buyer may roll over a particular section causing a roll-over screen to appear indicating the quantity and price range of tickets available in that section. By clicking on a particular section, the event listings may be filtered to display only the event listings in the selected section along with the specific details (e.g., section, row, quantity, price) for such tickets. The buyer also may zoom-in, zoom-out, drag, and/or rotate the interactive event venue seat map. [00911 When presented with the initial listing of all event tickets for sale, the buyer may filter the initial listing by inputting criteria such as one or more price ranges (e.g., $75 $286, $286-$349, $349-$442, $442-$559, and $559 and up). Once the buyer selects a price range, the event listings are filtered to display only the event listings in the selected price range. Additionally, the interactive event venue seat map is modified to display sections in color for which tickets are available in the selected price range. [00921 Each event listing may include ticket attributes such as section, row, quantity, and price. Each listing also may include a link to view additional details that when clicked may display the ticket attributes along with further ticket details (e.g., seat numbers, time remaining to purchase the tickets, seller comments, delivery options), a selectively enlargeable image of the event venue for reviewing the location of the seats, and an action button for initiating purchase of the tickets. [00931 To place an order for the tickets, the buyer may provide a delivery location, select a method of payment (e.g., credit card), confirm the transaction details (e.g., description of the tickets, delivery method, delivery location, payment amount, and method of payment), and the complete the purchase.When the buyer places the order, a confirmation e-mail is sent to the buyer, and the seller is notified of the order request via e-mail and requested to confirm the availability and delivery of the tickets. Upon receiving confirmation from the 26 )oc no 1000338678 seller that the tickets have been sent, the buyer is notified as to when delivery can be expected. It can be appreciated that upon the sale of the tickets, one or more delivery options may be available depending on the locations of the buyer and the seller, the time remaining before the event, and/or the form of the tickets (e.g., physical tickets, electronic tickets). Listing Catalog Services [0094] The listing catalog server 138 implemented by one or more of the application servers 130 may be arranged to receive and respond to queries and/or to provide access to event information stored in the events database 154. A query to the listing catalog server 138 may comprise, for example, a search query, web query, web feed request (e.g., RSS feed request, ATOM feed request), API request, HTTP request (e.g., Get, Post, etc.), a web form submission (e.g., XHTML/HTML form), and/or suitable request mechanism in accordance with the described embodiments. In various implementations, a query may be submitted to the listing catalog server 138 via one or more communications servers 120 from one or more client devices 104, client programs 106, a third-party server 114, and/or a third-party application 116. Queries also may be submitted to the listing catalog server 138 internally from other application severs 130 of the network-based system 110. [0095] In one embodiment, the listing catalog server 138 may be implemented by a distributed architecture comprising a plurality of distributed indexing modules. Each of the distributed indexing modules may provide an interface for receiving queries from front-end servers such as the communications servers 120. The distributed indexing modules may store and build updatable indexes against which a query can be checked to expedite retrieval of a query result. The indexes may comprise, for example, common keywords or search terms and event IDs linked to such keywords or search terms. The distributed indexing modules also may cache common query results. [00096] The distributed indexing modules may be arranged to receive updated indexing information brokered via a message bus from a local gatherer module. The local gatherer, in turn, may be coupled to and collect indexing information from the events database 154. The indexing modules may update and/or filter the indexes based on the updated information received from the local gatherer module and/or information from other indexing modules. 27 )oc no 1000338678 [00097] The local gatherer module may be arranged to periodically scan items stored in the events database 154 and obtain updated indexing information. For example, the local gatherer module may request items from the events database 154 that have changed within a given time period. The event information stored in the events database 154 may change frequently as new event listings for upcoming events are added and then removed when the tickets for such events listings are purchased. Furthermore, the events database 154 may store relatively static information for an event such as category (e.g., sports, concerts, theater), as well as real-time dynamic information such as current event listings and true levels of ticket inventory. It can be appreciated that the event information maintained by the events database 154 may be extremely dynamic especially in cases where LMS and electronic ticketing services are provided by the network-based system 110. [00981 The listing catalog server 138 may receive and respond to the queries with event information for upcoming events that satisfy such queries. The event information may be provided locally from the listing catalog server 138, if available (e.g., cached), and/or may be retrieved by the listing catalog server 138 from the events database 154. In various implementations, event information from the listing catalog server 138 may be communicated via one or more communications servers 120 to one or more client devices 104, client programs 106, a third-party server 114, and/or a third-party application 116. The event information from the listing catalog server 138 also may be provided internally to other application severs 130 of the network-based system 110. [00991 Exemplary event information parameters that may be included in the response from the listing catalog server 138 are described below in the following table. . 28 )oc no 1000338678 Event Parameter Details actprimary Home Team Mascot act secondary Away Team Mascot activejype 1 =active event 0= inactive event allowedtosell 1 =general public allowed to sell tickets = general public not allowed to sell tickets ancestorGenrelds List of parent IDs, in order of hierarchy, identifying browsing path to reach the node ancestorGeolds List of geography IDs, in order of hierarchy, identifying browsing path to reach the geography node canceled 1 =event has been canceled O=event has not been canceled channel Name of the top level genre in the breadcrumb trail tied to the event channelld ID of the top level genre in the breadcrumb trail tied to the event channelUrlPath URL path for the top level genre in the breadcrumb trail tied to the event channelfacetstr ID and Name of the top level genre in the breadcrumb trail tied to the event city City of the event date last modified Time of last change to the event description Name of the event eventDatefacetstr Month and year of the event, numeric (yyyy-mm) and alpha (month, yyyy) eventGeoDescription Name of venue event date Date and time of the event (GMT) event date local yyyy-mm-dd of the event event date time Date and local time of the event event id Unique ID of the event event time local Local time of the event genreUrlPath URL path for the parent genre of the event genreparent ID of the parent genre of the event geoUrlPath URL path for the venue of the event geographyparent ID of the parent geo of the venue hideeventdate 1 =event date hidden O=event date not hidden id ID of the event lastchance Date and time to delist the event used in place of the actual event date due to shipping rules maxPrice Highest ticket price for the event 29 )oc no 1000338678 maxSeatsTogether Maximum number of successive seats that can be purchased together minPrice Lowest ticket price for the event nameprimary Event match-up using team mascots (e.g., Mets vs Braves) namesecondary Full name of the away team (e.g., New York Mets) sparkeventflag Event marked as a "hot" event state State of the event totalPostings Number of actual postings for the event totalTickets Actual number of tickets listed for the event venue config id Configuration of the venue for the event Event Information Parameter Table [01001 It can be appreciated that, in some implementations, not all of the event information parameters included in the table may be necessary to present the requested upcoming event information to the user. Accordingly, when all of the event information parameters are included, the response may be parsed to extract only those event information parameters that are needed. Alternatively, the query and/or the response may be configured to request and respond with only those event information parameters necessary to display the requested upcoming event information. It also can be appreciated that the response may include different event information parameters and/or additional event information parameters than those described in the table. Dynamic Content Management Services [0101] The dynamic content management server 140 implemented by one or more of the application servers 130 may be arranged to provide a user with relevant and/or related dynamic content customized according to a particular context of the user. The dynamic event information may comprise, for example, event information that changes as new event listings for upcoming events are added and as event listings are removed when the tickets for such events listings are purchased and real-time event-specific information such as current event listings, price ranges, and true levels of ticket inventory. Relevant or related dynamic content may comprise, for example, dynamic content customized according to the location of the user such as location based advertising content (e.g., banner ads), relevant and/or related categories and 30 oc no 1000338678 subcategories (e.g., links for local sports teams, artists performing in the location, theater shows playing in the location), a list of event names and dates for upcoming events in the location arranged by category, and/or other type of dynamic featured content that changes according to the location of the user. [01021 In some implementations, the appearance of a user interface displayed to the user may be customized or branded with dynamic content based on the location of the user and/or event criteria specified by the user. For example, a web page or web client may comprise a comprise a header, skin, or other designated area that dynamically displays different graphics (e.g., pictures, logos, backgrounds, etc.), advertisements, news, and/or other featured content received from the network-based system 110 according to the location and/or event criteria of the user. [01031 In various embodiments, the dynamic content management server 140 may be structured, arranged, and/or configured to bind dynamic information to a particular node and/or combination of nodes defining the context of the user. Exemplary nodes may include, for example, geography nodes (e.g., event cities), category nodes (e.g., sports, concerts, theater), sports nodes (e.g., baseball, football, basketball), sports subcategory nodes (e.g., professional, college), music genre nodes (e.g., jazz, rock, alternative), theater subcategory nodes (e.g., musical, comedy), ticket subcategory nodes (e.g., regular season, playoff, bowl), conference nodes, team nodes, artist nodes, theater show nodes, venue nodes, event nodes, and so forth. It can be appreciated such nodes may be arranged (e.g., hierarchically) and/or in other ways in accordance with the described embodiments. [0104] The dynamic content management server 140 may be configured bind dynamic content such as relevant and/or related categories and subcategories, event listings for upcoming events, promotional or advertising content, UI graphics, and/or various other types of customized content to a node or combination of nodes. When navigating a web site provided by the network-based system 110, for example, the user may be presented with links for selecting from among various locations, categories, and/or subcategories and for viewing content associated with such selections. When the user makes a particular selection, the context of the user may be defined by one or more nodes associated with such selection, and the user may be presented with dynamic content customized to the context of the user. [01051 In various embodiments, the dynamic content management server 140 may implement a front-end query tool and presentation layer to query the listing catalog server 31 )oc no 1000338678 138 according to the context of the user. In response to the query, the dynamic content management server 140 may receive dynamic content (e.g., XML content) from the listing catalog server 138 and provide the dynamic content to one or more dynamic content modules embedded in a web page presented to the user. Accordingly, the content associated with event listings may change based on the context of the user, configurable parameters, and/or available inventory. [01061 In one example, a user selects a particular city, and the dynamic content management server 140 has bound dynamic content to a geography node associated with the particular city. Upon selection of the particular city by the user, the context of the user may be defined at least in part by the geography node of the selected city, and the user may be presented with the dynamic content that is bound to the geography node. In this case, the user may be presented with a web page including dynamic content customized for the particular city such as graphics (e.g., pictures, background) and advertising content (e.g., banner ads) for the particular city, relevant and/or related categories and subcategories (e.g., links for local sports teams, artists performing in concert in the city, theater shows playing in the city), a list of event names and dates for upcoming events in the city arranged by category, and/or other type of dynamic content that changes according to the city selected by the user. [0107] In another example, a user selects a particular football team, and the dynamic content management server 140 has bound dynamic content to a team node associated with the particular football team. Upon selection of the team by the user, the context of the user may be defined at least in part by the team node, and the user may be presented with the dynamic content that is bound to the team node. In this case, the user may be presented with a web page including dynamic content customized for the particular team. For example, the web page presented to the user may be dynamically branded with graphics (e.g., pictures, background), advertising content (e.g., banner ads), and/or news associated with the particular team. The user also may be presented with event listings for upcoming games for the team as well as relevant and/or related categories and subcategories (e.g., links for road games, playoff games) for the team. In this implementation, the context of the user may be defined by one or more other nodes in a hierarchical path to the team node such as a category node (e.g., sports), sports nodes (e.g., football), sports subcategory node (e.g., professional), and ticket subcategory node (e.g., regular season). As such, the user may be presented with dynamic content bound to one or more of 32 )oc no 1000338678 such nodes such as links to other professional football teams for which regular season tickets are available. [0108] It can be appreciated that the embodiments are not limited to the foregoing examples and that dynamic content may be bound to a particular nodes and/or a combination of nodes for customizing that content displayed to a user based on the context of the user. Accordingly, the dynamic content management server 140 may be used to create dynamic content campaigns including a various types of static and dynamic content and to bind such campaigns to nodes or groups of nodes that define a context of the user. It also can be appreciated that a node and/or combination of nodes can be detected as a user selects one more links and/or in other ways such as when a query is submitted (e.g., text entry, selection of checkboxes, selection from a pull-down menu), a search result is returned, or in any other way in accordance with the described embodiments. Payment Services [01091 The payment server 142 implemented by one or more of the application servers 130 may be arranged to effectuate and/or manage payments between buyers and sellers and to post and track financial transactions for users of the network-based system 110. Transaction information for past and pending transactions may be stored by the network based system 110 in the transaction database 156. The payment server 142 also may provide dispute resolution mechanisms to handle payment disputes arising between transacting parties and/or fraud prevention mechanisms to prevent fraudulent transaction, unauthorized use of financial instruments, non-delivery of goods, abuse of personal information, and so forth. While the payment server 142 is shown in FIG. 1 as forming part of the networked-based system 110, it will be appreciated that the payment server 142 may form part of a third-party payment system that is separate and distinct from the network based system 110 in alternative embodiments. [01101 In various implementations, the payment server 142 may account for a transfer of funds and/or financial value by debiting the a source of funds and/or financial value linked to the subscriber account of the buyer and crediting a source of funds and/or financial value linked to the subscriber account of the seller. For example, the network-based system may securely communicate with one or more financial institutions such as a bank or credit card company over one or more networks 108 and arrange the transfer of funds and/or financial value from 33 )oc no 1000338678 the buyer to the seller. It can be appreciated that while certain settlement mechanisms may be described for purposes of illustration, the embodiments are not limited in this regard, and a variety of settlement networks and modalities may be used in accordance with the described embodiments. [0111] In one embodiment, after the buyer reviews and confirms an order, the account (e.g., credit card) of the buyer is verified, and the sale amount (e.g., ticket price plus delivery cost) is authorized. The seller is notified of the proposed purchase by e-mail or other notification mechanism and requested to confirm that the tickets are still available and that the transaction can be completed. [0112] Upon receiving confirmation from the seller, the account (e.g., credit card) of the buyer is charged. Funds from the account of the buyer may be electronically transferred into a merchant account associated with the network-based system 110, and a transaction fee may be deducted. The remaining proceeds are then directed to the seller by issuing a payment in accordance with the payment method selected by the seller such as via check, deposit to a third-party payment services account (e.g., PayPalTM account), Season Ticket Account, and/or other type of source capable of receiving funds and/or financial value, and/or donation to a third-party such as a non-profit organization or entity. [0113] It can be appreciated that the network-based system 110 may provide a "double blind" complete ticket-sale transaction without interaction between buyer and seller. Namely, the network-based system 110 may facilitate an entire ticket-sale transaction without requiring any interaction between the seller and the buyer. The network-based system 110 controls and/or facilitates the entire sale and purchase process and serves as an intermediary between the buyer and seller effectively isolating the participation of the seller in the transaction from the participation of the buyer in the transaction. Accordingly, the identity of one transacting party can remain concealed from the other. Notification Services [0114] The notification server 144 implemented by one or more of the application servers 130 may be arranged to generate and send various types of notifications to users of the network-based system 110. The notification server 144 may communicate with users over one or more types of networks 108 (e.g., the Internet, a WAN, a WWAN, a WLAN, a mobile telephone network, a landline telephone network, a VoIP network, etc.) via interfaces provided the communications servers 120 such as the web server 122, API server 124, and/or messaging server 126. It can be appreciated that, in some implementations, 34 )oc no 1000338678 notifications may be forwarded to users via an intermediary such as an Internet Service Provider (ISP), online service provider (OSP), web-based e-mail service provider, message aggregator (e.g., SMS aggregator), mobile transaction network entity, and so forth. [01151 The notifications may comprise messages delivered to users via e-mail, IM, SMS, MMS, video message, telephone call as well as messages delivered to the subscriber account of the user. In some cases, the notifications may provide the user with information related to various online marketplace transactions. For example, notifications may be sent to sellers for indicating the status of event listings, informing the seller of offers (e.g., auction bids) for event listings or sales of similar tickets and allowing the user to modify the prices of event listings, notifying the seller of placed orders and requesting confirmation of the availability of tickets for such orders, providing delivery instructions and requesting confirmation of delivery, tracking shipped orders, providing the status of payments, and so forth. Notifications may be sent to buyers for tracking ticket purchase transactions (e.g., active bids, auctions lost) for event listings and allowing the buyer to modify offers, confirming an order and delivery, tracking shipped orders, providing pick-up instructions and requesting confirmation of receipt, downloading and print electronic tickets, and so forth. [01161 In accordance with various embodiments, sellers with one or more active listings may choose to and/or automatically receive transactional e-mail messages that complement and drive sellers to an interactive event venue seat map. The transactional e-mail messages may inform sellers that their tickets are still listed and that the event date is approaching and also provide a link to the online ticket marketplace and/or an interactive event venue seat map for the event to allow sellers to view the most recent pricing data. [01171 In some implementations, a buyer may subscribe to receive customized alert notifications for upcoming events as described in co-pending U.S. Patent Application Serial No. 12/262,468 titled "System and Methods for Upcoming Event Notification and Mobile Purchasing," which was filed on October 31, 2008 and is incorporated by reference in its entirety. In such implementations, the notification server 144 may be arranged to generate and send an alert notification comprising a text message including relevant static or dynamic event information as well as an embedded hyperlink. The hyperlink may comprise a hyperlinked telephone number for allowing the user to place a telephone call to an agent of the network-based system 110 for transacting a mobile purchase. Alternatively or additionally, the hyperlink may comprise a URL or URI for navigating to the network 35 )oc no 1000338678 based system 110 for transacting the mobile purchase. [01181 It can be appreciated that in some cases, an upcoming event may not satisfy all event criteria specified by the user. In some implementations, when there are no upcoming events that satisfy all the event criteria specified by the user, the user may choose to receive alert notifications for one or more upcoming events conditioned on the complete satisfaction of the event criteria. In such implementations, the network-based system 110 may allow the user to select to receive an alert notification whenever an upcoming event that substantially and/or completely satisfies the search criteria is listed. For example, the user may choose to receive "on sale" alert notifications when tickets that satisfy one or more preferences of the user become available. The network-based system 110 also may provide the user with various capabilities (e.g., preference settings and options) to allow the user to receive "on sale" alert notifications for preferred tickets and to allow the user to automatically and/or optionally purchase such preferred tickets. Delivery Services [0119] The delivery server 146 implemented by one or more of the application servers 130 may arrange the delivery of goods from the seller to the buyer. For the delivery of time-sensitive goods such as a single or multiple event tickets, the network-based system 110 may determine and present delivery options that ensure that an event ticket is delivered to the buyer before an event and the costs associated with such delivery options. [01201 In various embodiments, the network-based system 110 may coordinate the delivery of event tickets as described in co-pending U.S. Patent Application Serial No. 09/867,171 titled "System and Method for Providing Logistics for a Sale of Goods," which was filed on September 27, 2001 and is incorporated by reference in its entirety. In such embodiments, the network-based system 110 may automatically arrange and/or facilitate the logistics for the delivery of event tickets from the seller to the buyer. [0121] In one implementation, for example, when the buyer places an order, available delivery options are presented to the buyer that ensure that the event tickets can be delivered before the event either to the buyer or to a pick-up location (e.g., event venue will call or an office of the network-based system 110) in proximity to the buyer. The network based system 110 may determine all available delivery options based on the form of the tickets (e.g., physical tickets, electronic tickets), the time remaining before the event, the 36 )oc no 1000338678 location of the goods, the location of the buyer, pick-up locations in proximity to the buyer, and/or the capabilities one or more couriers (e.g., air/land couriers, express couriers, local couriers or "runners") that can execute the delivery within the time remaining before the event. [0122] When a physical ticket is to be delivered, the network-based system 110 may determine and present shipping options to the buyer. The buyer may provide a delivery or pickup location, and the network-based system 110 may automatically determine couriers capable of ensuring delivery and present a list identifying the couriers, the available shipping methods (e.g., two day, one day, overnight, same day) for each courier, and the associated cost of each shipping method. [0123] When a courier and shipping method is selected by the buyer, the seller may be notified and presented with a printable shipping label for the courier and logistics for providing the tickets to the courier. For example, the network-based system 110 may automatically determine the closest courier facility in proximity to the seller and may allow and arrange for the courier to retrieve the tickets. In such cases, the network-based system 110 may communicate relevant information (e.g., seller address, delivery address, pick-up day and time frame) to the courier in order to coordinate ticket retrieval. If the courier cannot service any of the selected locations at any of the selected times, the network-based system 110 may require the seller to drop off the tickets at the nearest courier facility. The seller also may select to drop off the tickets at the nearest courier facility. If the seller selects or is required to drop off the tickets, the buyer may be provided with the location of the courier facility, driving or walking directions to the courier facility, and/or a map showing the courier facility. [01241 Upon confirmation by the seller that the tickets have been sent or picked up, the network-based system 110 may communicate delivery tracking information to the buyer and/or seller. The network-based system 110 may notify the buyer of the delivery location and expected time and date of delivery. If the delivery location is at a pick-up location such as the event venue will call or an office associated with the network-based system 110, the buyer may be provided with the pick-up location, driving or walking directions to the pick up location, and/or a map showing the pick-up location. [01251 To ensure delivery to the buyer before an event, a last sale time may be associated with an event listing. In some cases, for example, the last sale time for an event listing may be three business days before the event to provide sufficient transit time to ensure 37 oc no 1000338678 completion of delivery. In such cases, the event listing will expire at the last sale time. Last Minute Services [01261 It can be appreciated that both sellers and buyers may desire the last sale time to be as close to the event start time as possible in order to maximize the opportunity to make a sale and the opportunity to witness an event. Accordingly, the network-based system 110 may provide sellers and buyers with various last minute services (LMS) for maintaining an event listing and the ability to sell and purchase listed tickets right up to the start of the event. [01271 In one implementation, for example, the network-based system 110 may allow tickets to be sold on consignment and may maintain an event listing until the start of the event. When a seller requires delivery of physical tickets for an upcoming event, the seller may select to sell the tickets using LMS provided by the network-based system 110. The seller may request LMS and provide the network-based system 110 with contact information (e.g., name, address, telephone number, e-mail address), ticket information (e.g., event name, event venue, ticket event dates, closest city to the event), and authorization to release the tickets. [01281 In response to the LMS request, the seller may be contacted by an agent of the network-based system 110 viattelephone or other contact method and provided with additional selling information. Depending on the time remaining before the event, the seller may be instructed to ship or physically deliver the tickets to an LMS center associated with the network-based system 110. Typically, the location of the LMS center will be in close proximity to the event venue. The seller also may select to physically deliver the tickets to the LMS center. When physical delivery of the ticket to the LMS center is required or selected, the seller may be provided with the location of the LMS center, driving or walking directions to the LMS center, and/or a map showing the LMS center. [01291 Once the tickets are delivered to the LMS center, the event listing may be maintained until the start of the event and the subsequent delivery of the tickets to a buyer is handled by the network-based system 110. For example, the LMS center and/or the network-based system 110 may handle the responsibility of shipping the tickets to the buyer, delivering the tickets to the event venue will call, and/or the keeping the tickets at the LMS center until pick-up by the buyer. It can be appreciated that the LMS provided by 38 oc no 1000338678 the network-based system 110 may facilitate delivery and allow the network-based system 110 to defer the last sale time until the start of the event. Electronic Ticketing Services [0130] In various embodiments, the network-based system 110 may provide electronic ticketing services for allowing a buyer to purchase one or more electronic tickets that can be used at the event venue. It can be appreciated that providing such electronic ticketing services may allow the network-based system 110 to defer the last sale time until the start of the event. [0131] When the user selects an upcoming event from event listings published by the network-based system 110, a web page may be presented to the user that includes event information for the selected upcoming event such as the name of the event, the date and time of the event, the event venue, available ticket listings including ticket attributes (e.g., section, row, quantity, price), and so forth. In some cases, a purchaser of event tickets may provide the event information to the network-based system 110 in order to list the tickets for sale on a secondary market. In other cases, the venue, event promoter, or other type of ticket issuer may provide the network-based system 110 with event details such as event description, event venue, event date and time, artist, and so forth. In response, the network based system 110 may manage the event, enable the venue to sell tickets for the event, manage the generation and distribution of electronic tickets, and facilitate the use of electronic tickets for access control to the venue. For example, the network-based system 110 may create an event listing, generate electronic tickets, publish available tickets for sale, and coordinate the sale of the electronic tickets. [01321 In various embodiments, a web page presented to a user may comprise the event information along with a link to purchase electronic tickets and/or a link to view additional details. By clicking the link to purchase electronic tickets, the user may initiate a purchase of one or more electronic tickets. By clicking the link to view additional details, a subsequent web page may be displayed including ticket attributes along with further ticket details (e.g., seat numbers, time remaining to purchase the tickets, seller comments, delivery options), a selectively enlargeable image of the event venue for reviewing the location of the seats, and an action button for initiating purchase of the tickets. In some cases, one or more web pages may include a link to view delivery options such as a location of, driving or walking directions to, and/or a map showing a pick-up location. 39 oc no 1000338678 [0133] To effectuate an electronic ticket purchase, the user may be prompted to enter account information such as a unique username or e-mail address and a password. Upon receiving the required account information, the user is authenticated with the network based system 110 and may initiate an electronic ticket purchase. After authentication, the network-based system 110 may transact the purchase using a source of financial value linked to the subscriber account of the user or may request the user to supply payment information (e.g., credit card account, PayPalTM account, etc.) for the transaction. [0134] In various embodiments, a user may purchase electronic tickets and/or save electronic ticket information using a web client such as a web browser, web browser toolbar, and/or a desktop or mobile widget. For example, a user may save an electronic ticket and/or a hyperlink to a file associated with the electronic ticket in a subscriber account, in the web browser toolbar, and/or within a desktop or mobile widget. The user also may display information for and differentiate among purchased electronic tickets on a client device (e.g., PC or mobile device) via the web client. [01351 The buyer may purchase one or more electronic tickets using a credit card or other source of funds or financial value linked to the subscriber account of the buyer. In one or more embodiments, the network-based system 110 may provide variable distribution and access control for purchased electronic tickets. For example, the network-based system 110 may provide the buyer with various delivery options for receiving and/or delivering the purchased electronic tickets. [0136] The network-based system 110 may allow the buyer to have the electronic tickets delivered to an e-mail address associated with the buyer. The buyer may access the e-mail account, display the electronic tickets, and print out paper copies of the electronic tickets. Each of the paper copies of the electronic tickets may include a bar code which can be scanned at the event venue to allow access. [0137] Alternatively or additionally, the buyer may instruct the network-based system 110 to send an electronic ticket to a mobile device (e.g., mobile phone or PDA) associated with the buyer. For example, the buyer may receive the electronic ticket at the mobile device and display a bar code of the electronic ticket on a screen of the mobile device which may be scanned at the event venue to grant access. In some usage scenarios, the buyer may receive an SMS message sent to a mobile device that includes a link to a web page to render a ticket. In other usage scenarios, the buyer may receive an MMS message sent to a 40 )oc no 1000338678 mobile device that includes an image of the ticket. When the buyer chooses delivery to a mobile device, the buyer also may receive the ticket via e-mail as a backup in case the buyer wants to print out a paper copy to bring to or use at the event venue. The buyer may receive a text message at the time of ticket purchase and, if the tickets are purchased more than a predetermined time before the event (e.g., two days before the event), a reminder text message just before (e.g., one day prior to) the event. [0138] In various embodiments, when the buyer purchases electronic tickets using a credit card, the buyer may access the venue by swiping the credit card used to make the purchase at the event venue. Alternatively or additionally, the buyer may use a driver's license to validate the ticket at the event venue. In some implementations, only the buyer may use the credit card used to make the purchase or a driver's license as a means of entry at the event venue. It can be appreciated that in such implementations, the buyer may validate his/her ticket at the venue as well as validate other purchased tickets for other people who are present with the buyer at the time of entry into the event venue. [01391 In various embodiments, the network-based system 110 may provide the buyer with various delivery options for splitting the distribution of a single order of multiple electronic tickets among one or more recipients in addition to and/or other than the buyer as described in co-pending U.S. Patent Application Serial No. 12/325,789 titled "System and Methods for Variable Distribution and Access Control for Purchased Event Tickets," which was filed on December 1, 2009 and is incorporated by reference in its entirety. In such embodiments, a buyer may ,purchase multiple electronic tickets (e.g., block of four electronic tickets) at once in a single order and choose to variably distribute one or more of the purchased electronic tickets and/or the underlying rights associated with one or more of the purchased electronic tickets to different end recipients using different delivery mechanisms (e.g., e-mail, SMS message, MMS message, etc.) or other suitable delivery mechanism. Upon delivery, each electronic ticket may be used by the recipient independently of the buyer arriving at the event so that the entire party does not need to be present to enter the event venue. User Interfaces [01401 As described above, the network-based system 110 may communicate with users 41 )oc no 1000338678 over one or more types of networks 108 via interfaces provided the communications servers 120 and provide various services to users such as online marketplace and ticket fulfillment services via the application servers 130 and databases 150. When servicing a user, the network-based system 110 may present information to and/or receive information from the user in a variety of ways such by displaying and receiving information via user interfaces (e.g., web pages, interactive screens), sending and receiving messages (e.g., e-mail, IM, SMS, MMS, video message), placing and/or receiving telephone calls (e.g., landline, mobile, VoIP, IVR calls), and so forth. User interfaces also may be displayed to a user via one or more client programs 106 such as a web client (e.g., web browser, desktop or mobile widget, web browser toolbar) and/or a third-party application 116 in conjunction with the buying services and/or selling services of the network-based system 110. [01411 With reference to FIGS. 2-7, various embodiments are described for building and presenting, at a user interface of a display of a client device 104, an interactive seat map of an event venue. In various implementations, the interactive seat map is built with tools that are compatible with and common to all web browsers such that the interactive seat map is able to be built and presented without the use of vector graphics such as Adobe® Flash®. [0142] It is to be understood that while a particular interactive seat map may be described in the context of the buying services of the network-based system 110, the embodiments are not limited to such context. Furthermore, it is to be understood that while a particular interactive seat map may be described as comprising a certain set of features and functions, an interactive seat map may comprise fewer features and functions, additional features and functions, and/or a combination of various features and functions of different user interfaces in accordance with the described embodiments. [0143] Referring to FIG. 2, the network-based system 110 stores inventory 200 of tickets available for an event at an event venue, a base map 205 that illustrates locations of sections within the event venue, and a coded image map 210 that will enable a client-side web application 215 at the client device 104 to build a map overlay 220 for the base map 205. In various embodiments, the client device 104 displays an interactive seat map 225 within a user interface 230 by loading the base map 205 and building the map overlay 220 on top of the base map 205. The interactive seat map 225 may be displayed next to and linked with rendered inventory 201 within the user interface 230 on the client device 104. [0144] Referring to FIG. 3, a logic flow 300 includes operations performed by the 42 )oc no 1000338678 network-based system 110 for enabling the client device 104 to provide the user interface 230 including the interactive seat map 225 and the rendered inventory 201 linked to the interactive seat map 225. [0145] The network-based system 110 (e.g., buying server 136) pulls the base map 205 from a database and transfers the base map 205 to the client device 104 over the network 108 (step 305). The client device 104, via the client-side web application 215, can store the base map 205 within memory for use at a later time. The base map 205 illustrates locations of sections within an event venue. The base map 205 can be in a raster graphics file format (e.g., JPEG or jpg, gif, png, bmp) such that the base map 205 is formed without the use of vector graphics formats (e.g., Flash@). [0146] The network-based system 110 also pulls the coded image map 210, which corresponds to the transferred base map 205, from a database and transfers the coded image map 210 to the client device 104 over the network 108 (step 310). The client device 104, via the client-side web application 215, can store the coded image map 210 within memory for use at a later time. The coded image map 210 is a coded redrawing of all of the sections in the corresponding base map 205. That is, the coded image map 210 is a series of polygons defined by coordinates such that it includes one polygon for every one section depicted in the corresponding base map 205. For a particular venue, there can be a few coded polygons to over a hundred coded polygons. [01471 Referring to FIG. 4, an exemplary base map 405 (e.g., JPEG image) illustrates locations of sections within an event venue that, in this case, is a baseball stadium. Exemplary portions of a coded image map 210 that is transferred for the base map 405 to the client device 104 are reproduced below: <area shape="rect" coords="160,41,175,46" href="#ink325vb" id="sec325vb" /> <area shape="poly" coords="176,41,186,41,190,43,190,47,176,45" href="#ink326vb" id="sec326vb' /> [0148] The first portion of the coded image map in this example is for a rectangular polygon displayed above Section 325 (labeled 425 in FIG. 4) of the base map 405. The second portion of the coded image map in this example is for a polygon displayed above Section 326 (labeled 426 in FIG. 4) of the base map 405. [0149] Next, the network-based system 110 pulls the inventory 200 for the event at the event venue corresponding to the transferred base map 205 from a database and transfers the inventory 200 to the client device 104 over the network 108 (step 315). The inventory 200 provides a block of data for each section of the event venue or for each section of the 43 )oc no 1000338678 event venue that has available tickets for the event, the block of data including section data such as a section identification (such as the section number), a section title (such as "Lower Box", "Field Club", or "Arcade"), and a listing of tickets (including the row, quantity, and price for each ticket). The inventory 200 can be encoded in a machine-readable form such as XML. Exemplary XML coding for inventory for Section 125 of the base map 405 is reproduced below: <?xml version="1.0" encoding="iso-8859 1"?> <sections> <section> <id>sec125</id> <sectionTitle> Lower Box 125</sectionTitle> <tickets> <ticket><row>A</row><qty>2</qty>< price>$85</price></ticket> <ticket><row>2</row><qty>7</qty>< price>$72</price></ticket> <ticket><row>5</row><qty> 1 </qty><price>$16</price></ticket> <ticket><row>22</row><qty>2</qty> <price>$5</price></ticket> </tickets> </section> 40150] After the network-based system 110 has transferred the base map 205, the coded image map 210, and the inventory 200 to the client device 104, the network-based system 110 awaits a ticket selection received from the client device 104 (step 320), at which point the network-based system 110 processes the ticket selection as described above. [01511 When transferred to the client device 104, the base map 205, the coded image map 210, and the inventory 200 enable the client device 104 to build a map overlay 220 for the base map 205. The client device 104 may then display an interactive seat map 225 within the user interface 230 by loading the base map 205 and building the map overlay 220 on top of the base map 205. The interactive seat map 225 may be displayed next to and linked with a rendered inventory 201 within the user interface 230 on the client device 104 [0152] Referring to FIG. 5, an exemplary interactive map 525 is built by loading the base map 405 and building a map overlay 420 on top of the base map 405. The interactive seat map 525 may be built with tools that are compatible with and common to all web browsers such that the interactive seat map 525 is built and presented without the use of vector graphics such as Adobe® Flash®. [0153] Referring to FIG. 6, a logic flow 600 includes operations performed by the client device 104 (e.g., via the client-side web application 215) for building and presenting the interactive seat map 225 for an event venue based on the information transferred from the network-based system 110 to the client device 104. [01541 The client device 104 receives the base map 205 (step 605), the coded image map 210 (step 610), and the inventory 200 (step 615), which includes, for each section, section 44 oc no 1000338678 data that includes available tickets within the event venue, from the network-based system 110. When the coded image map 210 initially loads, each of the polygons of the coded image map 210 lacks defining characteristics such as fill color, stroke color, or level of transparency. [0155] Next, the client device 104 builds the map overlay 220 on top of the base map 205 such that each polygon of the map overlay 220 aligns with the respective underlying section of the base map 205 (step 620). At this step, defining characteristics such as fill color, stroke color, and transparency for each polygon of the map overlay 220 have not yet been determined, so that the map overlay 220 may not yet be visible when the interactive seat map 225 is displayed (step 625). [01561 The client device 104 then determines one or more defining characteristics for each polygon of the map overlay 220 based on the section data, provided by the inventory 200, for the corresponding section (step 630). In particular, the client device 104, via the client-side web application 215, reads the inventory 200, finds all of the section identifications in the inventory 200, and matches section identifications in the inventory 200 with section identifications of the map overlay 220 to determine which polygons of the map overlay 220 requires defining characteristics. The inventory 200 determines the defining characteristics to apply to that polygon of the map overlay 220. A sample code from the inventory 200 is provided below for Section 324 of the base map 405: setArea~ver(document.getElementByld('sec324'),'cartography_canvas','237,24,72','237,24,72','0.5', 0,0,2) ;null, [01571 In this example, which is provided for Section 324, the client-side web application finds the section identification "sec324", matches that section (Section 324) with the polygon of the map overlay 220, and determines the defining characteristics corresponding to the section identification "sec324". The defining characteristics corresponding to Section 324 are a fill color of "237,24,72"; a stroke color of "237,24,72" and a transparency of "0.5". [01581 Next, the client device 104 applies the defining characteristics determined in step 630 to each polygon of the map overlay 220 (step 635). Thus, for example, and with reference to FIGS. 4 and 5, the map overlay 420 is built on top of the base map 405 so that each polygon of the map overlay 420 aligns with its respective section of the underlying base map 405 (some of the polygons of the map overlay 420 may not be visible since they lack any defining characteristics). The polygon 434 of the map overlay 420 aligns with 45 oc no 1000338678 Section 324 (labeled as 424 in FIG. 4) of the base map 405. The polygon 434 includes its defining characteristics such as a fill color of 237,24,72, a stroke color of 237,24,72, and a transparency of 0.5 (which is provided from the inventory 200, as shown above). In some implementations, other polygons of the map overlay 220 that lack any defining characteristics (and therefore are not visible in FIG. 4) represent sections of the base map 205 that lack any available tickets. [0159] Next, the client-side web application renders the inventory 200 as rendered inventory 201 at the display 230 (step 640). In particular, the client-side web application draws out the blocks of ticket listings below the interactive seat map 225. [0160] Referring to FIG. 7, a portion of a rendered inventory 701 is shown that corresponds to a portion of the coded image map for the base map 405 of FIG. 4. In this example, the rendered inventory 701 includes a block of data 750 for Section 324. Here, the block of data 750 includes the section identification 751, which is "324"; the section title 752, which is "View Reserve"; the listing of tickets 753, which includes the Row 754 (for example, A, 2, 5, or 22), the Quantity 755 (for example, 2, 7, 1, 2, respectively), and the Price 756 (for example, $85, $72, $16, $5, respectively) for each ticket available in Section 324. [0161] The client-side web application also establishes links from each section of the map overlay 220 within the interactive seat map 225 that has available tickets to the specific ticket group provided in the rendered inventory 201 (step 645). For example, when a buyer clicks on Section 324 (labeled as 424 in FIG. 5) of the interactive seat map 525, an established link between Section 324 and a specific ticket group corresponding to data block 750 re-directs the buyer to the data block 750, where the buyer can click the "Buy" link 760 to purchase one or more tickets in Section 324. [0162] If the client device 104 determines that one or more tickets have been selected for purchase (step 650), then the client device 104 sends the ticket selection to the network based system 110 for managing a transaction between the buyer and the seller. [0163] If no tickets have been selected for purchase (step 650), then the client device 104 can revert back to preceding steps if it determines that the ticket inventory 200 has changed since the ticket inventory 200 was initially received at step 615. [01641 It can be appreciated that while a logic flow may illustrate a certain sequence of steps, other sequences of steps may also be performed in accordance with the described 46 oc no 1000338678 embodiments. Moreover, some individual steps of the logic flow may include multiple sub steps that may be performed in various sequences as appropriate to the individual step. Furthermore, additional steps may be added or some steps may be removed depending on the particular implementation.
