Hi, have just come across a gift receipt that accompanied a baby jacket which was a duplicate gift. I had assumed I hadn't been given a gift receipt and just resigned myself to an unfortunate doubling up, and it has sat in the wardrobe, still with tags, since. However, I found the receipt today in the bottom of a bag which the gift had come in. The final date for returns was 2/5/11. How likely do you think M&S are to flex that, given I would be happy to exchange it rather than just take a refund?
