I didn't know this, but it doesn't surprise me in the slightest. I received my own LE blu-ray of The Thing from Amazon with no problem but only this week they stiffed me on my Sorcerer preorder; luckily that wasn't a limited edition item and I was able to get down to the nearest HMV to pick up a copy (for £5 less than Amazon were asking) but they've become properly unreliable now. Is it because I'm not an Amazon Prime member, I wonder? I had to have a real set-to with them prior to them delivering my Lone Wolf and Cub set (two days late and in complete contradiction with any tracking information I had) as well. The thing is, treating me like a second-class f*cking citizen isn't exactly filling me with any incentive to sign up with them. It's just the retail version of a protection racket, and all it's doing is pushing me increasingly back to a high-street retailer who also has an online store too.
It's a bastard though because Amazon's range is still second to none. Amazon Marketplace stuff still seems pretty good tbh, it's just stuff straight from Amazon that appear to have become a bit of a roll of the dice.
