They have addictive personalities when it comes to food. I don't think it would end. Ever see someone who is addictive to shopping who is shopping while a sale is going on? It's the same thing "These belts are 75% off so I bought 10 of them and then that gives me points on my rewards card which means I'll get extra coupons." "Uh...what are you going to do with 10 of the exact same belt?" "...Look how cheap they were!"
