If you are an Amazon prime member, unless you visit gaming blogs regularly you probably haven't heard of this deal. For all "physical games" you buy on Amazon . . . you get a discount. The offer is 20% off for all video games you pre-order and when you buy the games early [within 2 weeks of release]. The offer however is available only to U.S residents/the U.S Amazon store at least for now. It may be extended elsewhere [to other countries] after some time.
