How We Verify Coupon Codes Before Publishing Them

Our process for testing, dating and retiring offers, and why we publish the exclusions rather than only the headline percentage.

Most complaints about coupon sites come down to the same thing: a long list of codes, no dates, and no indication of which ones have any chance of working. We built our process around fixing that, and we publish it so you can judge how much weight to give what you read here.

Where offers come from

Offers reach us from retailer newsletters and press releases, publicly published promotional pages, merchant programme feeds, and reader submissions. Every source is treated the same way: nothing is published on the strength of the source alone.

What we check before publishing

A member of the deals desk builds a real basket at the retailer and attempts the offer. We record whether the code validates, the minimum spend it needs, the discount cap, which categories are excluded and whether it requires an account or new-customer status. If we cannot get the offer to validate, it does not go live.

We then write the terms in plain language. The point of an offer page is not to repeat the marketing line, it is to tell you the conditions you will run into at checkout before you have spent twenty minutes building a basket.

Dating and re-testing

Every offer page shows the date we last re-tested it. High-traffic offers are re-checked on a rolling weekly schedule; the rest are re-checked at least monthly and whenever a reader reports a problem. Offers that fail re-testing are removed rather than left up with a stale date.

Reader reports

The report link on each offer page goes to the deals desk. We aim to re-test reported offers within one business day. If an offer has been withdrawn we take the page down; if the terms have changed we update them and re-date the page.

What we will not do

We do not publish codes we have not been able to validate, we do not invent expiry dates to create urgency, and we do not describe an offer as exclusive unless a retailer has issued it to us specifically. We also do not redirect you through tracking hops to see a code: the code is on the page.

None of this makes us infallible. Retailers change promotions without warning and regional variations are easy to miss. But a dated, tested listing with the exclusions written out is a far better starting point than an undated wall of codes.

One email a week. Only offers we have tested.

A short weekly summary of the offers our deals desk rated worth using, and the ones that have expired. No daily mailouts, and every email carries a one-click unsubscribe link.
