Don't you have seller protection for physical goods? Usually ebay will give you your money back, either that or Paypal
All of that is BS with eBay, they don't protect the business. The only protection is if the buyer says they haven't received the item and providing you send it to the address and it is tracked, and the guy turns around and says he hasn't had it, then ebay will pay you. But, seriously, eBay are beyond safe in offering that kind of protection. Whereas buyer protection is crazy. They can do anything they like and business sellers (not private) get royally screwed.
