How we test a code before it goes live

4 min read · Verification team · September 19, 2026

Every coupon code that appears on YallReviews has already been through a live checkout — by a person, not a script. Here's exactly what that process looks like before a code earns its PASS stamp.

Step 1: Sourcing the code

Our team pulls codes directly from merchant partners, official store campaigns, and public promotions. We don't scrape aggregator sites or copy codes from forums, because those sources are often stale by the time they're indexed.

Step 2: The live checkout run

Before anything goes live, a member of our verification team adds real items to a cart on the merchant's own site, enters the code exactly as submitted, and confirms the discount actually applies at checkout. If the code doesn't work, it never gets published.

Step 3: The stamp

A code that survives the checkout run gets marked PASS and a reference number, shown on the site as a small barcode next to the offer. That reference lets us track exactly when a code was last confirmed working.

Step 4: Re-checking every 24 hours

Codes expire without warning. Merchants change promotions mid-week, limit codes to first-time customers only, or simply run out of budget for a campaign. That's why every live code gets re-tested on a 24-hour cycle. The moment a code fails a check, it's stamped VOID immediately — not when a shopper complains.

Why this matters

Most coupon sites publish whatever a scraper finds and let shoppers discover dead codes themselves. We'd rather show fewer codes and have every one of them actually work.
