You still can apply to get some of the VAT back at the airport. I do this all the time. I keep my little "Tax Free Card" that I got at the airport. It has my country of residence, passport, address and other info. Then I get all the documents I need and present them for a refund at the airport. I don't get all the VAT returned but it is worth my trouble to do so. Just have to make sure I am at the airport early enough to get it done. I have to show my items to customs before I leave (but not always).
