Did they actually shut her down? My experience with eBay is that they will do nothing to sellers who rip off buyers who pay by check. The goal is to make you use Paypal, which is now owned by eBay, so eBay gets yet another cut on the deal. On the other hand, they will automatically side with the buyer in a dispute if Paypal is used.She took the money and ran. Ebay was basically of no help on this. They actually said, 'Sorry but we can't MAKE someone sell you something... ' How nice, again. All they could do was shut down her account, like I'm sure she really cared. Lesson from this: USE PAYPAL.
Enough complaining about eBay and Paypal. eBAy is a good place to find stuff. Your best protection is the Seller's feedback. Check it out. If they have a lot of sales and a high feedback rating, you should be ok.
