Ebay is a system if you know how to work it only people’s initial bids will determine what you pay.
As an example, say a lot of games goes up starting at $.99 for 7 days and this lots estimated value is $100. I want it but I don’t bid till the last 20 seconds so I watch for now, by day two it has say 4 bids and is currently sitting at $5.50 with someone on the winning side with a max bid of say $25.00 because like the OP he wants to get the lot cheap. He sits with the winning bid all the way till the end, So he assumes that hes going get a great deal when he wins. He might sit there with the mouse on the “1 click bid” button but if no one has pushed past his $25 bid by now why would they? So he keeps his max bid where it is. Then someone like me comes and in the last 20 seconds and puts a max bid of $90. The guy doesn’t know what to do he was so sure it was won he might have enough time to do one or two “1 click bids” but not enough to put in a new max bid. So now I just won a $100 lot for about $29 and if another sniper did it for more than $90 I wouldn’t have time to even try another bid and would lose or if bid up to my max I would pay as I was willing to do from the start.
