Paypal offers nex to no protection for sellers. They greatly, greatly favor the buyer. There is seller protection but it regularly fails. What’s worse is that as a seller you have to deal with credit card chargebacks that paypal has no control over and can be dragged out over months and even years. If the buyer defrauds you(more often than not) and wins the credit card chargeback(which they normally do b/c CC companies don’t want to lose customers), Paypal will come to YOU looking for the money. There are plenty of stories of Paypal bringing collections agencies against people. Oh, and they also charge a fee against you if you get a chargeback against you(even if it’s a fraudulent one that is eventually found in your favor.
Avoid using paypal unless you absolutely need it.
I will add though that all the paypal help center people I spoke to on the phone were prompt and spoke English as a first language. I just wish their ToS didn’t make it so easy for buyers to defraud people.
