I bought 3 toy items on the 3 for 2 promotion. One of the items was for my nephews Christmas present but I found out he already had this gift. I went online and bought another toy for a similar price. I then presumed that I could refund the newer item and exchange that for the duplicated gift. The store advised I would need to get the refund online. I contacted customer services and was advised that as I had got the duplicated gift as the free item, if I returned this item I would not get a refund. I advised that I didn't want to refund I just wanted to exchange for the other item I had bought online. I spoke to a Manager and he said the same thing. So lesson learnt I will not buy any online products from Tesco again as it appears that their refund policy is not as easy as it states on the website.
