Hiya - I bought my Mum a Joss sTone cd for mothers day but i bought the one she already has and gave it back to me to get her the other one for easter. I bought it in tesco's and once when i took a dvd back there they refused to give me a refund and said their policy was to exchange it only. Can they do that? We're especially broke today so i was hoping to get a refund and buy the other one next week!!
