I believe Best Buy is matching Amazon.com prices. This is a good thing for everyone. I stopped buying things from Amazon because sometime their packaging description turned out to be different than what they ship. This happened to me twice, the last time it was for the BATTLE ROYALE "Book" packaging - instead they sent me a standard Bluray case. Sometime they ship blurays without "slip" covers, so basically if you're looking for a particular packaging - I wouldn't order it sight unseen.
Anyway, I picked up Barbarella Blu-Ray for $10, with a nice fold-out slip cover. Granted, some people don't like the slip covers - but personally, I like it. This special/limited slip cover is semi-glossy and has indents/popup. Opening the fold, reveals more artwork. For $10, it's cheaper than tracking down the original DVD release.
As for the movie, it's a pretty silly movie. What can you expect from a film based on a French adult comic book? Lots of nudity, including Jane Fonda, and surprisingly rated only PG, not PG-13 or R.
And man, who wouldn't want to fonda Jane?
