Auction Sentry Deluxe has everything that Auction Sentry has and more.

In addition to tracking your eBay auctions for you and placing your bids at the last moment (referred to as sniping) the Deluxe Edition features a built in browser, support for conditional bidding or "Bid Groups" and extended support for multiple eBay user IDs. The new Bid Group feature lets you set up several snipes on similar auctions to be executed until one of them wins (automatically canceling the other pending snipes).

Whether you're a buyer or a seller this eBay tool streamlines and automates the transactions you make on eBay. 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. It tracks all of your auctions and has a configurable refresh rate to keep all information displayed current alerting you when an auction you are tracking receives a bid. A must-have serious eBayers!
