Not strictly christmas although it does relate to a christmas item...Does anyone know if you buy an item when it's discounted and then need to change it for a different size but it's no longer discounted can you do a straight swap or do you need to pay the difference? Just done myseld out of around £6 by exchanging a gift but requesting the value to go onto a giftcard first (as was returning 2 items and only wished toexchangeone of them) instead of a straight exchange. Gutted!
