I'm paranoid of bootlegs
I think Amazon is one of the places where bootleggers can get away with that kinda stuff but I'm not exactly sure, I've heard stories of it before but have never had any experience with it happening to me. The one you linked to actually seems pretty legit, I mean it has everyone's names on it and I don't really know if bootleggers can do that without their permission. My only problem with it is the price, that seems way too good for it to be a blu-ray and the entire series. I'd say buy it from the official website but I don't think they ship to UK. Whatever you do though, stay away from shit that looks like this.
Would someone who owns it please post pictures of each disc and of the inside and outside of the package?
(I don't own it but I can make a pretty good guess.) From this one I'd say it would be pretty standard, nothing special included with it.
Also how's the picture quality?
Picture quality should be really good if it's 1080p (It's a blu ray so it probably will be).
I'm sorry I can't really answer any of your questions, I decided to throw my two cents in if no one else was going to do so yet. Hopefully someone way more helpful than me can direct you the right way.
