Well I was looking for a cover for my new purple kobo and came across this. Not sure why but the pink and red are only 1p plus delivery.
If you buy more you save lots, for example 2 cases come to £4.31 and 5 cases come to £7.34 (less than £1.50 each!)
You can see the exact same model going for £7 in black. Reviews for the black one are here http://www.amazon.co.uk/Navitech-Black-Leather-eReader-WHSmith/dp/B00719WX76/ref=sr_1_7?s=electronics&ie=UTF8&qid=1337817273&sr=1-7
