Just as a heads up: it’s against PayPal’s TOS for the seller to charge you the PayPal fee! (which is another strike against this artist for sure) if an artist tries to make you pay it, inform them about the TOS violation and don’t pay it. It could get their account shut down, and also it’s just rude to do??? sellers are using a service to accept payments and there’s no other fees that have to be paid besides per-transaction ones.
also I hope they either refund you or complete the art they owe you 😕
