I believe that you have to spend over £50 in each store you visit in order to claim your VAT refund - so unless you are planning on buying everything in the Body Shop, you may be better off picking it up VAT-free at the airport (a savings of 17.5%) Duty-free alcohol does offer a much deeper discount...

leroy - I'd love the duty-free shops within the EU to remain, but that does seem to circumvent the spirit of the common market... If I were still living in the UK and doing a lot of European travel I would fill out one of those forms every time I went through an airport... but somehow I think that it won't last forever.
