I sold something on Ebay and I'm still waiting for Paypal to send me my money. That was three months and many emails ago. So . . .I've been using PayPal since it's inception and it's the safest way to transfer money in a transaction like you describe. In order for the seller to use PayPal, they have to have a confirmed account, which means PayPal has their banking information. PayPal also has a lot of consumer protections associated with it, and if there are issues with any transaction, they are very serious about your protection as a consumer. If anything, I would trust a PayPal only transaction over and above just about anything else.
Yes, it does, though the language is quite general with regard to exactly what, giving them wide latitude for assigning terms of use violations. Quote from PayPal "Acceptable Use" agreement list of prohibited transactions (linked in my post above):.... Does PayPal specially prohibit only firearms themselves or does it extend to accessories as well? That’s quite a catch 22 if it does.
(j) ammunition, firearms, or certain firearm parts or accessories
