Not DVDs, but I've semi-recently started buying my movie tickets through Fandango using the AMC A List, so I'm still not paying anything while getting Fandango rewards. After every 4 movies you get a $5 off coupon for their marketplace or off a movie (in hindsight, should have used it for Weathering With You Fathom, but still hopefully that at least hits the AMC 24 after the Wednesday/Thursday showings), so when I get one I just poke around their sale movies To Own For $5 Or Less. Thus far, this is what I've got, plus the order in which I've 'purchased' them:
Slither
The Cabin In The Woods
That's My Boy
You're Next
Perfect Blue
