Answer:
The item on sale already has a discount
Explanation:
Usually coupons offer discount on items a store sell but they have indications that state that they are only valid for full-price items. If you want to buy a item that is on sale, the coupon won't be valid as the item already has a discount included and the store won't give an additional discount on that product.
The customer can't use the coupon because it has expired.
