I'm starting to get frustrated...I sold a designer bag and wallet 7 days ago, sent the buyer an invoice with a nice message thru e-bay right away on Friday, June 1st. I didn't hear anything until Monday when I get a message saying "can I send you a check?" Well my auction clearly stated PayPal only and I messaged back saying that. On Wednesday I get another saying "I don't have PayPal" so I sent her another message telling her to send me a certified check by Priority mail. So far nothing back from her. What should I do?
