Basically, print the voucher off, go in store and spend any amount on your AMEX card. Take your receipt and the voucher to customer services to get your free £10 gift card.. simple!
Alright there will probably be a lot of comments about it not being the cheapest place to shop, but they have some good buys like everywhere else right now! And there food hall is excellent for Christmas luxuries. ... Anyway I am sure some cheapskate will search the store till they find something for 50p (like a bag), get the gift card and give it to there missus for xmas !! (Not that I would ever do that ;) )
