It's the danger with these mystery boxes. You have no idea what you're getting and if it's a load of stuff you don't want or have already then you may as well sell it on to recuperate some of that money. (I don't usually buy them.)
This is why I don't buy mystery boxes/bundles. I'd rather not risk getting a release I already own/have no interest in getting, and going through the hassle of selling them on CeX or Cash Converters (I usually go with the latter whenever I give away some anime DVDs and upgrade to Blu-ray for those titles, as my local Cash Converters pay out more than CeX).
