All of our gas stations /convenience stores have these, which works out great because all pepsi products, 20oz bottles are 2 for $2.22. In fact they've had BF3 on the DrPepper label for well over a month here. But none of the grocery stores have the marked bottles.
A heads up, I redeemed everything but the wolf pack for PS3 yesterday, and they all were the proper codes, that was about 4pm EST.
I will get some cap codes and share them next week, a lot of DrPepper drinkers at work with me (Pop machine @ work is loaded with the 20oz bottles). I haven't been grabbing caps because I thought they were going to stick it to us PS3 and PC players like they did for BF:BC2, but I will start to grab them and post them up.
