Ebay+PayPal is a pain nowadays! I myself try to keep any high-value item off it.
Some time ago I had an issue with a bloke in Malaysia, sold a vintage Seiko on eBay, 55 days later i get a message he never received it.
eBay says a buyer must open a case within 45 days from sale date BUT it gives the buyer 60 days to leave feedback, so essentially the buyer can get a refund even after the 45 days, like what I had to do , on top of that , if +45 days pass you will NOT get neither your Ppal nor eBay fees back even though you give a full refund. Bloody ripoff that , a very nice loophole for eBay/PayPal to ensure they keep their fees.
