Welcome to the community.
I keep hoping that people would understand that the object of the game is to get the best possible price for a mystery auction. When you bid up the price by $50, $100 increments early on in the bidding, it only drives up the price of the auction. As I had mentioned before, this is a Dollar auction and the real bidding really only takes place at the end of the closing. If someone wants to win the auction really badly, this would be the time to bid $100 and more.
