I see the VAT is now up to 24%. Wow! I know I can't get a refund for the VAT at restaurants, hotels, etc... but I can for purchases I bring home if they are over 120 euros. Is that cumulative, or is it just for single purchases over 120 euros? If the former, do I get a refund by keeping all my receipts and showing them to an official at the airport while leaving the country? Or, something else?
