MSRP can usually be confirmed by GS(which has updated to $30) but something is not right. I just clicked on the X360 version & it came up $39(not $39.99) & when I refreshed & did both the PS3/X360 again they were $39.99.
I have no idea. I'm not even sure if the $30 is MSRP or whether it was a sale or glitch or what. But a few times back Best Buy has had games for free due to the coupon and a sale, such as Deadliest Warrior and TERA. The next day, the prices went back up. Now even though it's not free, I have no idea what Best Buy will do with Prototype.
I really hope BB didn't re-adjust a MSRP just b/c of a coupon, I can understand the Deadliest Warrior reasoning but not for this.
