Coupon fine print: "one per purchase" vs "one per transaction"

Every coupon has a line of small type that tells you how many times it can be used. Most people skip it, which is how a plan for six coupons turns into one at the register. Three phrases come up again and again. They sound alike and mean different things.

"Limit one coupon per purchase"

In couponing practice, "per purchase" is read as per item purchased. If you buy three eligible items, you can use up to three of these coupons, one on each. This matches how store policies describe coupon limits: Kroger's policy, for instance, says one coupon per item purchased, and Walmart's says one paper manufacturer coupon per item.

What "per purchase" does not mean is unlimited. The store's own limit on identical coupons still applies (more on that below), and so does any quantity limit printed elsewhere on the coupon.

"Limit one coupon per transaction"

A transaction is one checkout: everything rung up between the first scan and the receipt. A coupon marked "one per transaction" can be used once in that checkout no matter how many qualifying items are in it. If you want to use a second one, it has to go into a separate transaction, and whether the store allows that is up to the store and its daily limits.

"Limit one per customer" or "per household"

This one attaches to you, not to the checkout. Splitting your order into separate transactions doesn't reset it. Digital coupons tied to a loyalty account usually behave this way automatically: once you redeem a clipped coupon, it's gone from the account.

The store's identical-coupon limit

On top of what the coupon says, several large retailers publish a cap on identical coupons per household per day. At the time of writing, Walmart's policy says 4 identical coupons per household, per day unless the coupon says otherwise, and that there's no limit on the variety of different coupons in a transaction. Target, Walgreens and Dollar General publish similar household-per-day limits. If a coupon prints a stricter limit, the coupon wins.

Steps: reading a coupon in thirty seconds

1. Find the issuer. "Manufacturer coupon" or the store's name. This tells you which policy applies to stacking.
2. Find the limit phrase. Per purchase, per transaction, or per customer.
3. Find the qualifier. Size, variety, quantity ("when you buy two") and any excluded items, such as trial sizes.
4. Find the date. Walgreens, for example, says coupons expire at 11:59 p.m. local time on the expiration date in store.
5. Check the store's daily cap on identical coupons.
6. Count. Now you know how many to bring.

"Buy two" coupons and BOGO sales

A coupon that says "save when you buy two" needs two qualifying items to redeem once. Using it with a store's buy-one-get-one sale is where policies differ most, because the second item may ring up free. Some retailers address this directly in their coupon policies, and the rules aren't uniform, so this is one to read on your store's page rather than assume.

Common reasons a coupon won't scan

• The size or variety doesn't match the description.
• The coupon has expired, or a digital coupon was clipped after checkout.
• It's a photocopy or screenshot. Dollar General and Walmart both say they refuse these.
• It's a manufacturer coupon on a phone at a store that only accepts paper. Walmart's policy says manufacturer coupons are not accepted on digital devices.

When the cashier reads it differently

Phrasing on a coupon is the manufacturer's, but enforcement is the store's. If you and the cashier read a limit differently, ask for a supervisor and point to the specific line. If the answer is still no, that is within the store's rights under every policy we read. Take the note for next time and move on.
