I just sold an item and took a paypal payment on it. The guy that bought the stuff used a credit card through paypal. Paypal deducted about 3% of the payment for what I guess was a processing fee. So they charged me nearly 6 bucks for a $190.00 payment. I didn't realize they would do this so I stuck to the deal but next time I will warn the buyer he has to add the processing fee if he wants to make a payment with a credit card. The $6.00 wasn't that big of a deal but if it was a more expensive item I would've hated it.
