Clinton cards currently have 20% off a £25 gift card. They also have a seperate promotion (no code required) giving £5 off a £25 spend - so you can get one £25 giftcard for £22.75 or two for £37.75. Link to product here: http://www.clintoncards.co.uk/gifts/...=1838&x=29&y=7
There is also a free p&p code, but I couldn't get it to work. FREEPP - supposed to expire at the end of this month.
