Yeah, do you guys have any moviestops nearby? that's where I buy almost every movie I buy? They have thousands of movies Used and new. And the used ones are as low as 1.99 and usually never more than 14.99. Actually the vast majority of DVDs there are 4.99, 5.99, and 6.99.
Also they usually have a deal going on, buy 3 get 1 free. I've walked in there before, spent 40 bucks, and walked out with 8 good condition movies.
Seriously, I never have a problem with the discs. And the packaging is usually in good condition.
I got Short Cuts used on Criterion for 8 bucks I think. And it was perfect condition.
