I sell and buy on proxybid. The auction house Just Average Goods bounced a $800 check from my consignment items. I refused to pay for my items one in that weeks auction. I will not do business with companies that bounce checks and also our contract was breached when they did. Proxybid in there ultimate wisdome kicks me off of proxybid for not paying that weeks items one. They can bounce my consignment check but I still have to pay my weekly items one?
