This sounds like fun. You purchase 3 specially marked boxes of Kellogg’s cereals. Go to the Kellogg’s site and enter the codes found inside the boxes. Wait 4 to 6 weeks for the Bucks to arrive. Then go spend them at participating stores. There is a long list of stores and even some movies available. There are only 4 cereals with codes inside. These are: Froot Loops, Mini Wheats, Frosted Flakes, Raisin Bran. You have until 09/30/2010 to do this so that is almost a year. I think I can eat that much cereal in a year.
**I was not able to find out if you can do this more than once but we can always try.
