There was one time that I was obsessed bidding and I want to cancel my bid but I would still wait till someone outbid it and this takes forever. This could also be helpful if you wanna change your bid or change your mind and dont bid that so that you can bid another item you want that is cheaper.
Um, that's how bidding at an auction works. You can't say "Oh, I changed my mind" and take your bid back. And obviously you can't bid more crowns than you have- if you win both auctions, how are you going to pay up?
