Amazon offers Prime members Straight Outta Compton on Blu-ray / DVD / Digital HD for $9.99 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $4.98.) That's tied with our June mention and the lowest total price we could find by $5, outside of the mention below.

Don't mind going to the store? Best Buy has it for the same price with in-store pickup.
