My guess is that he bought it in the Pearson's sale, and didn't realise the medium size was so big. If he sells at £220, it means he would have lost £5 on his purchase. Thats my guess, but I'm a cycnic, and distrust most sellers.
EDIT: Buying from someone here on this forum (ASM) is different; as you can ask others for their input, and find out more about the seller.
