The IVA had nothing to do with eBay, from eBay I only paid the shipping and the item. It's just that in costumes I had to pay the IVA (each country has its own denomination for this but its that tax over every product, IVA translates to "added value tax"), back then it was 19% now it's 21%, I don't know if I had to pay some extra costumes fee. A friend of mine usually buys things from Canada, he told me they cheat the taxes and that he only pays the value of the item and the shipping, however apparently, ether the seller didn't know how to do this, or in the US they can't do the same thing.
