I just sold a Carly on eBay with a buy it now and the buyer is a BRAND NEW user, just registered TODAY!! What should I do to protect myself?! I'm so terrified that I'm going to get scammed. I listed Paypal as the only accepted method of payment. Should I be wary if she pays with eCheck (I've heard that buyers can retrack payments or something)? Should I require that she pays with credit card? HELP!!
