Just bought the iPhone app and set up my first snipe on an item on ebay I'm bidding on. As my max bid was already placed on eBay, I'm now worried my snipe will bid against myself! Anyone know what happens? Thanks :-/
You can not bid against yourself on eBay.
If nobody bid higher, your snipe will not even increase your current bid as long as you snipe using the same eBay user id.
