The listing, 3 caps-> 3-15,000 Facebook Game Credits!!! has ended.
I have 3 caps from 7-up with codes that you enter for Facebook game credits. Each code can be anywhere from 1-5,000 credits and you have 3 chances to get possibly get the maximum value, making your chance at either 3-15,000 total. You can use these credits to buy virtual goods in games and apps on Facebook.
