Because of the wonderful new EU Vat laws (yes, I'm being sarcastic) I've had to change the way the download store works. Basically the EU has decided to change the way VAT is charged for electronic download sales between EU countries. Up till now, when selling to another EU country you would charge vat based on the address of the seller, in my case Ireland. However, starting on the 1st of January, you now have to charge VAT based on the address of the buyer rather than the seller.
