Paypal not cover seller at all. As I wrote here, sold a knife to ebay buyer, shipped insured to him in safe plastic envelope which is not possible to open without damage. Buyer claimed he received 2c shit not a knife. Paypal frozen my money - I've made a investigation with my and also France post office (buyer was in France) both confirmed envelope was delivered without damage.
Buyers sent 2c shit back to me, provided tracking number to Paypal and they take my money and sent to him.
Paypal was not inteersted that post offices confirmed not damaged package, not even about weights of my and him packages differs!
Post office did not filled insurance because package was not damaged.
For a money paypal earn every day on horrible fees and currency conversions they should be more detailed in their investigations. Every call I've made in those days was with different employee and I had to describe it from start all which was quite lot of money for a phone calls
