That's me, exactly!
It doesn't make me mad so much that someone is willing to pay more for an item than I am, but how they go about doing it. Just when you think you are really getting a deal, some creep comes in at the last second and outbids you.
I don't bid on many items early because I know that the bidding only begins in the waning moments. I watch, then if I want something, see where the bidding goes. If it goes out of sight near the end, there is no use in me even bidding. I go there for two reasons; to get something I can't find anywhere else or to find bargains.
In the case of the former, I often place my bid earlier for what I'm willing to pay or email the seller to see if they have a buy it now price in mind to end the auction early if they don't have one listed.
