I was browsing trying to find something that puts me over the top for the $50/$10 Digital Gift Card deal and looked up American Dad season 7 out of curiosity. It was $9.99 as were all the other seasons. I investigated further and also noticed the other shows listed in the title are also all $9.99. There may be more, but The Simpsons and South Park are not among them. Arrested Development Seasons are also $9.99 each. They are not advertised nor are there any sale tags in store, but they do ring up at $9.99. I bought FG Season 9, American Dad 7, Bob's Burgers, and Cleveland Show 2.
Also, The Killing Season 1 on Blu Ray is $9.99
And yes, this is Best Buy
