This sounds like a huge pain in the ass to maintain, and will be ripe pickings for fraudulent sellers. eBay sucks, but they have a lot of horsepower at their disposal to deal with people gaming the system. Their 10% fee on the sale is too much though. If you want to throw a bunch of time at something on this site, fix the Pinside store problems and figure out how to integrate a domestic and international shipping calculator into the individual listings, using USPS and UPS through Paypal. UPS shipping rates are significantly cheaper when purchased through paypal.com/shipnow. Pinside is losing a ton of fees because this has not been figured out, and most orders must be completed off site.
