I recently sold my xbox 360 and now have my HD-DVD drive left with 5 hd dvd's. 4 of these are sealed and are form the 5 free dvds offer. I was looking at the price cex offered for them and it was £5 each!! i was offered £8 no longer than 2 weeks ago. I was wondering if anyone has tried taking them to a dvd store such as HMV and trying to take them back there. This way they would give you around £17.99 each as you could say that they were bought as a gift and had no receipt. Would they take them?
