The problem is paypal, they ask a 3,4% fee + 35cents. Anyway, still made some profit.
Later I wanted to spend this paypal money, but the money was frozen.
according to paypal they just hold onto it for a month to be sure everything went right.

But there are other ways, you could tell your customers to only pay through bank wire(no fee in Europe) or BTC and mark the item payed manually.
That way you will be avoiding fees.
