> see the fairly uniform pricing of products sold in euros between countries, despite varying vat rates between eurozone countries.

Huh, not sure I agree with that (the uniform pricing thing). I mean, one should believe that, but it doesn't appear to be true. For example, recently I saw a tablet for 208 euro (converted from GBP) on amazon.co.uk, approx 220 euro from amazon.de and 360 euro from amazon.ie, for the same item.

I was really surprised because I figured electronics would be pretty similarly priced across the EU/UK, but apparently not.
