coupon issued by a store to guarantee the price of a product advertised in the flyer but out of stock when the customer is shopping
- A rain check must be issued to customers who so request when a product is out of stock.
- A rain check must be issued no matter what product is out of stock or what department is involved.
- A rain check is valid at all times.
In some specific cases, such as when the season of the product in question ends, a merchant may offer another product of the same kind and of equal or superior quality at the same price, instead of a rain check.
