If someone has bid higher than you bid it will tell you that you are outbid. When you bid, it only shows the amount you have to bid to be able to win the auction. So, if it says that I have to bid 121 to win the auction and I bid 175, everyone else is only going to see that the bid is at 121. Then, there is a little playing room and someone can't outbid me in the last few seconds of the auction as quickly.
