What a load of bologna.
iTunes prices are not at all ridiculous. I'm pretty sure the most expensive movie I have seen is $20. You go into stores like Target and Walmart and you'll see a many BDs more than $20. As far as "older movies" for less than $14.99, you apparently don't check out their weekly sales. This week there are a bunch of action movies that are $7.99, including the Kill Bill movies, Machete and Gangs of New York.
As far as competitive prices in general, Gone Girl is $15 on iTunes, $18 on BD from Amazon. Lucy is $15 on iTunes, WILL BE $23 when its released on BD on iTunes.
And complain all you want about rental pricing because that's set by the movie studios. Google Play, Amazon and every pay TV provider will charge the same prices on those rentals. If you like Redbox, fine. But there are only so many titles that can be stored in any given box and you still have to actually travel to a location to find the movie.
