Yeah, sniping is really a fun way for buying stuffs on Ebay. I have won a few auctions by sniping and the differences in $ for bids I put in compared to the next highest bids were usually $0.01. Just won an auction for a mobile phone 3 days ago by sniping.
OP may wonder how it is done? Here is how, usually by guessing how much the highest bid may be during the last few seconds of an auction ending, I just put in a bid of $0.01 more, then the auction ends and no one else would have time to do anything after that. If it turns out my guessing is right I would win the auction, otherwise I would lose, there is no certainty that I would win every time.
For a few items I bid and won with $0.01 differences, that was because my guessing was somehow correct. So the process of sniping and winning an auction is more based on your luck and experience rather than cheating because you really haven't got a clue of what the next highest bid is in order to put a higher bid before an auction ends. So, there is no cheating and can't complain.
