It seems as though NewEgg understands that you’ll be spending a ton of money this Fall because they want to help you save $12.
By heading over to this page of upcoming PS3 releases or this page of upcoming PS Vita releases, choosing the game you like, and then entering the promo code EMCJNNH224 at checkout, $12 will be reduced from your order.
The fine print on this offer does state that it is ‘Not valid on open box and refurbished items. Up to a maximum discount of $12.00 per order. No minimum purchase required; promo codes may only be used once per order but can be used multiple times per account and cannot be combined with other promo codes or discounts. Only available while funds last. Promo code expires on 10/04/2012 or sooner based on fund availability.’
Basically, you can buy as many games as you like, they just have to be on separate orders.
