Promotions end, but printed coupons keep circulating. A flyer with "20% off this weekend" sits on a fridge for months, and when a customer finally scans it, they find either an expired deal or, worse, a discount you no longer want to honor. Static codes leave you with no control once the paper leaves your hands.
A dynamic code gives that control back. When a promotion ends, point the code to the next offer or a friendly "this deal has ended, here's what's on now" page. You can pause a coupon that is being shared too widely, or run a series of offers through one printed card. The paper lasts; the deal stays current.
Where to place it
- Bag stuffers or receipt inserts, offering a discount on the next visit.
- Counter signs near the register for upsells and add-on deals.
- Local newspaper or newsletter ads, each with its own code for comparison.
- Product hang tags announcing a bundle or buy-more-save-more offer for that item.
- Loyalty or punch cards linking to the current member-only deal.
Tips that improve scans
Put the value in the call-to-action
"Scan for 15% off your next visit" beats "Scan for a surprise." People scan promotions when the benefit is concrete and stated right beside the code.
Always show the end date
Display the end date on the offer page, not only on the print. When you swap offers later, the page itself explains what changed. It avoids confusion.
Plan the after-page
Prepare a "this offer has ended" page that shows current deals and a mailing list sign-up. Switch to it the day the promotion closes, rather than leaving a dead link.
Keep it scannable on small pieces
Bag stuffers and receipts are held in hand, so 2 cm (0.8 inch) works. For counter signs read from a step away, use 4 cm or more.
A shoe store handles an expired sale
A shoe store printed two thousand bag stuffers with a code for a back-to-school discount. The sale ended in September, but customers kept scanning the stuffers through October. The manager had planned for this: on the last day, he repointed the code to a page announcing the autumn boot collection with a smaller discount for newsletter sign-ups. Late scanners found a current offer instead of a dead end.
