Why are you amazed? You paid just over 10% in fees, how much do you think you would have paid if you had sold it for the same price in an auction house, how much do you think it would have cost you to advertise it nationally in a newspaper?

IMO ebay FVFs fees are perfectly reasonable at 7.9% and Paypal is one of the cheapest 3rd party payment portals and I doubt if anyone would have paid that much if they couldn't use a safe payment method.

All the fees are there for you to weigh up before you list and nobody forces you to use ebay.
