Bid higher, or get a sniper program.
I have placed sucker bids many times. Sometimes you get lucky and win. But don't expect a really low bid to win on any particular day.
That's the tricky part of Ebay I think. Knowing yourself. Knowing how much you are going to miss losing out on something. I wanted to get a King of Mercia frame for my Sis that was up for bid just days ago. The timing, for me, sucked. I spent a lot on Xmas, I should have just sucked it up. It happens.
