2. Save coupons that you know you can still use (whether they have an expiration date or not).
3. Don’t use coupons to buy more than you realistically know you can use before the item expires (food or beauty product).
4. Don’t use coupons if it’s going to mean that you have to buy more than you have space to keep (Do you really have room for eight bottles of ketchup?).
5. Don’t always assume just because you have a coupon, it’s the best deal. Compare prices before you toss it in your cart. Sometimes, there's a more economical option than the product with the coupon's discount.
