4. You have a stockpile that could literally feed an army.
No one can say it better than coupon expert Jill Cataldo: â€œIf youâ€™re buying more than you can use before the expiration date comes around, itâ€™s time to stop. For example, cereal has about an 11 to 12 month shelf life. If you eat a box of cereal each week, and you wanted to buy a yearâ€™s worth of cereal at once, are you really going to need more than 52 boxes? But some people buy a couple of hundred boxes. Remember that these sales repeat. There really is no reason to go that crazy. In about 8 to 12 weeks thereâ€™s going to be another sale.â€
