i was bidding on this book and its the high bidder was bidding 6.40 so it i needed to bid 8.40 or more. so i put my bid in and confirmed it but it showed that i was outbid by the same bidder. it showed he had bid 8.50 then. but last time i looked it was the 6.40. i kept doing it just to make sure i mistaken it and it did it again. it was like the person set his account up to where he was the high bidder no matter what. is that possible?
