A: If you use eBay proxy bidding, it makes your initial bid KNOWN immediately. Others will see your interest in the auction, which will most likely start a bidding war, drive price up early on and generally lower your chances of getting the item of interest. On the other hand, if you use SniperFox- it will place your bid at the latest possible moment before the auction ends ("snipe" it), making it less likely that another bidder will reply. This method results in final price reductions of about 30% on average.
