Whether you are a buyer or a seller, this online auction tool can streamline and automate the transactions you make through eBay. Auction Sentry automates bidding by placing your bid as close to the end of the auction as possible (referred to as "sniping"). The intuitive interface displays your auctions in a color-coded grid, indicating which auctions you are winning, which you have been out-bid on, and which you have set up a snipe bid for. Auction Sentry tracks all auctions and has a configurable refresh rate (five minutes by default). Auction Sentry can also be configured to alert you when an auction you are tracking receives a bid.

The latest version features a host of updates including support for all of the European eBay sites, the ability to run on non-English installations of Windows, a newly updated help file, ability to load auctions from your My eBay Item's I'm Watching page, the ability to export your auctions file to Excel and the ability to print out your auctions list.
