Know what you mean Mark, but I always check BOTH Amazon and DeepDiscount. Almost seems like their split; half the time, Amazon's cheaper, other half Deep's cheaper.
But Amazon's customer service, return policy, item packaging, etc. beat DDD hands down. I do use DDD, but only when it's not an essential DVD and the price is MUCH lower.
I too check Amazon and DDD (there were a couple of other titles I almost added to my Amazon order, but they were much less at DDD, while a couple of titles that I did add were much less at Amazon). However, my experience with DDD's customer service and return policy has been excellent. (I don't think I've ever had a need to contact Amazon's Customer Service.)
Problem with DDD's returns is that you need to send back the item first and they'll send you a replacement, and overall it's a pain in the ass process. With Amazon, you call them up or email them, and a replacement item is sent 2nd Day mail to you that same day, you print out a return label and send the damaged item back in the box the replacement came in. Very cool, the best return policy there is. Most others require you first to send the damaged item back before they'll send you the replacement.
I just got this in the mail from my regular import shop and after viewing it I have to say it's a stunning movie (with very nice packaging). I haven't seen the theatrical release, so I can't tell where the additions are, but I thought the opening overture as well as the entr'acte on the second disc was a pretty classy move by Scott.
Oh, and the DTS track made my neighbour complain (never had that happen before ).
