Our 7-point verification process

Every promo code on DealHarbor passes through the same seven checks before it goes live, and the entire catalog is re-tested every Tuesday morning.

1. Source authentication

An editor confirms the code came from a legitimate source: a brand press release, a partner email sent to a verified marketing list, an official loyalty-program announcement, or a reader submission with documented proof of redemption. Codes that surface only on third-party coupon sites without a primary source are not eligible for publication, full stop.

2. Incognito booking replay

The editor opens a fresh incognito browser window — no cookies, no logged-in account — and navigates to the brand's official booking site. This eliminates the risk that the discount is appearing because of a returning-visitor cookie, a personalized rate, or an account-linked benefit that ordinary readers wouldn't see.

3. Promotional rate surface check

The editor enters the promo code into the brand's "Special Rates" or "Promo Code" field, runs a search against representative travel dates, and confirms that a promotional rate appears in the room results. If the search returns the same Best Available Rate as without the code, the code does not pass.

4. Discount math validation

The editor compares the promotional rate against the unrestricted Best Available Rate for the same room type, dates, and property. The discount must match what the code claims to offer — a "20% off" code that delivers an 8% reduction does not pass. We round down rather than up; a code that advertises 25% off but delivers 23% would be re-headlined as "Save up to 25%" or rejected entirely.

5. Geographic and date sampling

For chain-wide codes, the editor samples at least three properties across different regions and three different travel windows (this weekend, three weeks out, three months out). Codes that work in only one region or one window are flagged with explicit fine print or rejected.

6. Loyalty stacking check

The editor logs in to a loyalty account and confirms that points and night credits accrue on the discounted rate. If the code disqualifies loyalty earning, the coupon page calls it out explicitly so you can decide whether the cash discount is worth the foregone points.

7. Terms read-through

Finally, the editor reads the promotion's full terms and conditions on the brand's site and surfaces any meaningful restrictions on the coupon page — blackout windows, minimum stay requirements, cancellation rules, and combinability with other offers. We aim to put the fine print where readers will actually see it, not buried in a tooltip.

Weekly re-verification

The catalog is re-tested every Tuesday morning, with a smaller spot-check on Friday afternoons. Codes that fail two consecutive cycles are removed automatically. Codes that have been verified in the last seven days carry a "Recently verified" badge on the coupon page so you can prioritize them.

Reader-reported failures

If a reader reports a failed checkout via the contact form, that code is moved into a review queue and re-tested within one business day. We respond directly to the reader with our findings — either the code is genuinely broken (in which case we remove it), the code requires a small adjustment (such as a date shift), or the code is working as intended (in which case we expand the fine print to make the restriction clearer).

What we don't promise

We don't promise that every code will work for every traveler in every situation — hotel pricing engines are too volatile for any coupon site to make that claim honestly. What we do promise is that the code worked at the moment our editor tested it, that we'll remove it quickly if it stops working, and that we'll never publish a code we couldn't independently verify.
