Coupons: Addictions and self control

I don't feel that I have scary addictions like illegal drugs or alcohol but I think I'm addicted to simple carbohydrates. What are you addicted to? If you receive a coupon for something you're addicted to... would you have the self control to tear up the coupon and throw it away? Sometimes I receive coupons for chocolate chips. I don't think I've ever been disciplined enough to rip it up and forget about it. I guess the key is to put my "self control" in the drivers seat so I won't buy something I'm addict to just because it's a fair price. Doe's money play a part in whether or not you buy and consume something?
