Amazon offers Prime members Bioshock: The Collection for PlayStation 4 or Xbox One for $29.99 with free shipping. (Best Buy charges the same for the PS4 version. Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $4.98.) That's $30 under our September mention, which was bundled with a $25 Dell gift card, and the lowest total price we could find by $10. It includes BioShock, BioShock 2, and BioShock Infinate, each with all single player DLC.

Update: The deal at Amazon has ended; however, Best Buy still offers the PS4 version for $29.99 with free shipping.
