Gift cards sit by every checkout lane in America, from the drugstore to the warehouse club, and stores promote them harder than most of their actual merchandise. The reason is that a gift card changes when a retailer gets paid.
The sale happens before the goods move
When a shopper buys a fifty-dollar card, the retailer collects fifty dollars immediately but hands over no inventory. The transaction is cash in, with the obligation to supply goods deferred indefinitely.
Accounting rules do not let the store call that revenue yet. It is recorded as a liability, a promise owed to whoever eventually walks in holding the card.
Even so, the cash itself is real and usable right away. A chain sitting on a December surge of card sales has working capital months before it delivers anything in return.
A share of the value is never claimed
Some cards are lost, forgotten in a drawer, or spent down to a stray balance too small to bother with. That unredeemed portion is known in the trade as breakage.
Breakage is the cleanest margin in retail because there is no product cost against it. The store keeps money without shipping, staffing, or restocking anything at all.
State escheat laws complicate this. Many states treat long-dormant balances as unclaimed property that must be turned over, so the retailer's share depends heavily on where the card was sold.
Redemption usually costs the buyer more
Shoppers rarely spend a card down to zero. A card worth twenty-five dollars tends to be used on a purchase that runs past it, with the difference paid by another method.
That overspend is ordinary full-price revenue attached to a sale that might not have happened. The card functions as a floor under the basket rather than a ceiling.
Retailers also find that card holders shop differently. Money that already feels spent is treated more loosely than cash from a checking account, which pushes the basket further upward.
Cards recruit customers the store did not have
The buyer and the user are usually different people. A parent buying a card for a coffee chain hands the brand a recipient who may have never visited a location.
That makes the card an acquisition tool with negative cost. The store is paid to introduce itself to somebody new rather than paying to advertise to them.
Third-party racks at supermarkets extend the same effect. A restaurant that cannot afford shelf space anywhere gets a slot in a store visited weekly by everyone nearby.
Federal rules set the outer limits
Congress restricted the worst practices roughly a decade and a half ago. Store-branded cards generally cannot expire quickly, and dormancy fees are limited in how soon and how often they apply.
Those protections apply unevenly. General-purpose prepaid cards carrying a payment network logo follow different rules than a card usable only at one merchant.
The economics survived the regulation intact. Free float, breakage, overspend, and cheap customer acquisition all remain, which is why the rack near the register keeps growing.
