Maybe you just have to bid higher, I dunno. I always do my bids at the last 10 seconds. I bid my absolute "worst case scenario"highest bid. I put it in at the last 10 seconds. That way if I win, I win. If I lose, it was the most I wanted to pay, and I don't end up bidding any higher than that.
Is he buying every RG out there? I guess if you bid high enough, you will win, and if you don't you have the satisfaction of bumping his price up at the last minute. I have 2 windows open. I make my bid in the one, and it sits on the confirm screen. In another tab I have the item, which I refresh and watch the countdown. Once it hits around 12 seconds, I switch to the confirm and put in my bid. That way if someone else is watching, the bid pops in at under 10 seconds and they might have time to fumble in a last bid. Usually not. The only guitar I lost out on lately was a PMC.
