I have used PayPal many times for Ebay purchases and had absolutely no problem. I have not used it as a seller, only as a purchaser. There are no fees for purchasers, only for sellers. And I believe that if you use bank accounts only (not credit cards) for transactions, there are no fees period.
Works for me. It's a great concept. If PayPal screws it up, others better at executing the concept will take over.
Since you haven't been ripped off
yet, I'll put you down as PayPal cheerleaders. If you are ever unlucky enough to have a problem there is absolutely no way to get through to them to rectify it. They don't respond to emails, there are no numbers on the site, and their fax is disconnected.
Beware.
