I used paypal years ago, still would be, if they didn't freeze my account for firearms transactions. paypal will absolutely not allow a firearms transaction, their right. They froze a few thousand of my money because I sell firearms and had a transaction. The problem was, the "transaction" I had was not firearms related. The stole my money for months, I quit them.
Interestingly paypal will allow transactions for porn and drug paraphernalia but finds itself a moral compass regarding firearms. I'll never use them again and wish them the worst.
