Sold out of the sale item? How rain checks work

You drive to the store for the advertised deal and the shelf is empty. Before you pay full price or give up, know that grocery stores have a federal rule behind those weekly ads, and a rain check is one of the ways a store can meet it.

Key takeaways

Federal rule 16 CFR 424 covers advertised items at retail food stores (food, grocery products and other merchandise they sell).
A store that runs out isn't in violation if it ordered enough for expected demand, or offers a rain check, a comparable substitute, or other equal compensation.
Ads that clearly say supplies are limited or the item is only at some stores are outside the rule.

What the rule says

The FTC's 16 CFR Part 424, Retail Food Store Advertising and Marketing Practices makes it an unfair or deceptive practice for a retail food store to advertise products at a stated price if the stores covered by the ad "do not have the advertised products in stock and readily available to customers during the effective period of the advertisement," unless the ad "clearly and adequately discloses that supplies of the advertised products are limited or the advertised products are available only at some outlets."

The rule then lists four defenses. A store is not in violation if:

It ordered the advertised products "in adequate time for delivery in quantities sufficient to meet reasonably anticipated demand";
It offers a "raincheck" for the advertised products;
It offers, at the advertised price or a comparable discount, a similar product "at least comparable in value"; or
It offers "other compensation at least equal to the advertised value."

What that means at the store

The rule is about grocery and food stores. It covers what they sell, including non-food merchandise, but it doesn't cover every retailer. Department stores and electronics chains set their own policies.
Read the fine print in the ad. "Limited quantities," "while supplies last" or "at participating stores" takes the ad outside the rule.
A rain check is one option, not the only one. The store can instead offer a comparable substitute at the sale price or other equal compensation.

How to ask for a rain check

Bring the ad (paper or the store's app) showing the price and the valid dates.
Ask at customer service before the sale ends. Ask whether there's a quantity limit and how long the rain check is good for.
Ask about a substitute. A comparable size or brand at the sale price may be faster than waiting.
Keep the slip with your list and use it before it expires. Some stores let you use it only once.

Stack it with other savings

A rain check locks the sale price; manufacturer coupons may still apply on top, depending on store policy (see our coupon stacking guide). Always compare the per-ounce price, since a "deal" on a smaller package can cost more (see unit price math), and watch for shrinkflation.

If an ad keeps advertising items a store never seems to have, you can report it to the FTC at ReportFraud.ftc.gov.
