1) It’s confusing. eBay doesn’t work this way, and really everybody’s expectations about how “internet auctions” are supposed to work are based on eBay’s proxy bidding. I kept bidding the same bid over and over again, to see if this was a bug. If your max bid is 200,000 and I bid 100,000 the current high bid should at least have to beat 100,000.

Yes I noticed this too. I put a high bid but got beaten with a lower bid. The “maximum bid” seems to only work for the first bidder I think.
