I use PayPal because the tools for dealing with not received and “(S)NAD” [(significantly) not as described] products is so easy for customers. Credit card chargebacks are far more difficult and tedious, and often they insist you send back a NAD item via a “trackable method,” which then could incur shipping costs sometimes greatly exceeding the value of the item.
I understand PayPal has routinely forked over sellers since crooked customers lie, but I’m not one of those. I’m also an eBay seller.
