Earlier quoted context omitted.
PayPal is known to protect the buyer over the seller. The buyer already purchased the violin. The buyer wanted a refund, but the seller refused and stated there was no refund for it. The buyer then filed a complaint with PayPal where PayPal told the buyer to destroy the eBay guaranteeing the $2500 back.
Thanks for the answer. A system that allows for this kind of abuse might need checking over, can't say I get why that's allowed at all. Anyone ever seen this used in the right manner? (if such a way to use this method exists.) It just makes so much more sense to send the item back.
Basically you can think of PayPal as a credit card. The buyer is always protected over the seller. So as long as you, as a buyer, don't abuse your right, you'll be able to get away with a few claims.
