I sell on eBay through my store. Never start so low. It will only take 25 Cent increments and you will never reach the $40.00. If you look in the seller details, it explains how much a bid will increase per the starting price. I learned this the hard way. By the way, what is the machine? I am kind of looking. I know too that $40.00 is just about the right shipping expense. Good luck!
