I don’t know any firearms enthusiast that uses PayPal for anything gun related. Sadly, it is a bit more convenient than getting money orders, so often I gift to people I know/trust if I need to buy something and get it here in a timely manner, rather than wait to get money order, send it out, wait for them to get it, wait for them to deposit it, and wait for them to ship and then me receive.
There’s been a company or two that created a gun-friendly version of PayPal, but they went under fast due to shitty customer service and not giving people their money.
PayPal CAN do that because face it, there’s no other options like it. BoA on the otherhand, who is in a very competitive market (even though they are one of the leaders in it) with many other options, people can afford to switch accounts.
