Online sniping service Bidnapper has added new features this week offering cash back on purchases, and integration with UnWired Buyer.

The cash back feature, called "Buyer's Club", helps users to participate in cash back programs to receive credit for purchases.

The UnWiredBuyer function allows users to monitor the final minutes of an auction when they are away from their computer. The system calls them by phone in the last 3 minutes and announces the auction status including the current bid amount. The user may also place a bid on eBay over the phone, by following voice prompts, if bidding has gone above the snipe value they have set.
