Amazon is currently offering $10 credit towards the future purchase of a video game after you pre-order Bioshock 2 for Xbox 360, Playstation 3, or PC.

The highly anticipated video game sequel will be released tomorrow, February 9, so you have to get your pre-order in before the end of today.

Also, the pre-order price has been discounted: Xbox 360 is $54.99; PS3 is $55.99, and PC is $46.99 (a 6%-8% discount). It’s unclear whether those sale prices will continue once the game has been released.

To get the pre-order credit, make sure you order directly from Amazon, not from one of their third-party merchants. For full details on the offer, click ‘Special Offers Available’ under the price section on the product page.
