Today I purchased The Wind Rises BR+DVD from CEX.
I promise you that I'm not a CEX shill, but God, they always come through for me if I'm looking for something. eBay users and other second-hand sites asking £15 for a used Blu-ray copy, CEX £5 +£2.95 delivery.
I've got a good chunk of out of print stuff from them as well at good prices. I know they sort of get a bad rep, but I haven't had a bad experience yet (aside from 1 Blu-ray that had disc rot, which I was able to get fully refunded at my local store, under their 24 month warranty on everything they sell, so it wasn't exactly a bad experience per se). The only bad thing is that they charge delivery on per item now.
I hope they keep on going,
