I got screwed the same way. I won a special edition C64 pack and paid $30 shipping (which should have been enough). The seller didn't send for a month or so and then finally says I need to pay $20 more because she mis-calculated. I refused and asked for a refund. After another month still nothing so I filed complaints with PayPal, eBay/SafeHarbor, and my credit card company. PayPal and CC couldn't do anything because too much time had passed. eBay didn't care that I had been ripped off (ie. I didn't have any product, or my money), and basicly took the sellers side. Eventually, I got the C64 but without the extras that were offered in the auction. (As well as a retaliation negative feedback.) Good luck with your situation, it seems the buyers are always on the losing end.
