Has anybody entered the Win a sports den contest from Kelloggs? You can purchase Cheez it's and Pringles amongst other things and enter. There are a ton of instant prizes available. My question is has anybody entered more than once? Can you use the same receipt? I bought several boxes of Cheezits on one receipt and want to know if I can enter more than once. I read the rules but I'm not any further ahead. Help, any one? Thanks so much!!!!
