You all do know Blockbuster filed for bankruptcy this week? So, I wouldn't trust any services from them, let alone support for an app, anytime soon until they come out of it as a smaller company.
The sooner the retail industry accepts the idea that brick and mortar stores are no longer necessary, the soon we will get better apps to get products to us.
I would be happy with a RedBox app that gave me locations, movies available at a location, and reservations.
