The site tells you that once you have bid up to the price of the item, you can not bid any longer but can buy now. Using this reasoning on at least three occasions, I watched a site until the bidding was down to two or three bidders. Knowing that these bidders were getting close to their bid limit, I entered the bidding but found that the bidding kept going against one last bidder who should have long ago bid out. I think the site has an employee bidding against you with no bid limit. What a rip off.
