My husband is frantically looking for these (and driving me nuts in the process ). It's an EA Games / XBOX 360 Promo that has pins inside the caps of bottles and under a sticker on Big Gulp Cups in 7-11. You can input the code online and get special items in various games, such as Mass Effect and Battlefield Bad Company 2.

If anyone find any pins please PM me. Trade rate is $2 per pin. I have Pizza Pops, Armstrong Cheese, Black Diamond Cheese and Nestle Ice Cream (plus loads others) for trade. Check my sig for my trade list.

The promo is called "Every Bottle or Cup Wins" or something similar.
