Oh, and if you buy items > £100 or so, keep the receipt and item in your carry on bags at the airport so that you can reclaim the tax back (VAT/tax in UK is 20%). You can search online for 'VAT reclaim uk' for more information.
I think it's actually required per Visa/MC to ask for ID, but not 100% sure on that.
