That was my point - you wouldn't see a VAT tax on your purchase. I have paid VAT taxes many times in England as I went there numerous times over twenty years. Whatever I bought had the tax added to my bill - right there to see. I kept all the receipts. Since I was not a citizen of England, when I left the country I went to a VAT tax location at the airport and they refunded to me all the VAT tax I had paid on purchases.
