Right now Target has American Sniper Blu-Ray combo pack for $12.49. There's also a 10% off all movies offer on Cartwheel (and of course it stacks with RedCard 5% off if you have that).
Price also valid online:
Kingsman Blu-Ray is also the same price.
Birdman Blu-Ray is $10 before Cartwheel.
Noticed this wasn't even posted on Blu-Ray.com's price checker so figured I'd point this out. The DVD of American Sniper is priced very similar so it is possible this is another Target "oops" where they priced their Blu-Rays at the DVD price so if interested I wouldn't wait.
