If you are only spending a small amount and a coupon is burning a hole in your pocket then use it, but don’t just use a coupon when you are making a small purchase if you know you will return to the store before the coupon expires. If you have a coupon and are going to use it anyway… wait until there is a better sale so you can get more mileage out of your coupon. If you have a 20% off coupon and use it for one item that is not on sale that is less than $20 you won’t maximize your savings. Use the coupon when items you want are on sale and get an additional discount. Combine coupons with gift cards and rewards purchases and you can really save a bundle.
