A surge is a store running far above its own normal — not a big store being big. Every retailer below is measured against its own trailing 4-week baseline and shown as a demand index (typical week = 100), so a small brand having its biggest week ranks ahead of a giant having an ordinary one. Bot-driven weeks are excluded and stores that spike every year in the same season are vetoed — what's left is demand that's verifiably unusual, the week it happens.
As of August 15, 2026, the sharpest-surging store on SimplyCodes is Good Good Golf — shopper demand at 3.3× its own typical week in the week of August 3, 2026 (demand index 100 → 331).

Methodology
How SimplyCodes verifies codes. Behind every figure in this live data study is the SimplyCodes verification system. Coupon codes are tested at real checkout before they are listed, through three independent layers: daily automated testing, where headless browsers runs headless browsers through real checkout flows and records whether a discount actually applies. A human verification network of 10,000+ verifiers submitting screenshot-and-timestamp proof, at 4.6M+ verification actions a month and 98% accuracy. And a real-time fleet signal feeds live checkout outcomes back into the engine. A code counts in this live data study while it is tracked in SimplyCodes verification data.
How this radar is built. We compare each store's shopper demand on SimplyCodes in the week of August 3, 2026 against that same store's trailing 4-week median, and publish the result as a demand index where the store's own typical week equals 100 — so a 250 reads "2.5× its usual demand", and no store is ever compared against another store's traffic. A store makes the board only when the surge is high-confidence: enough history to establish a baseline, bot-influenced weeks excluded, and stores that spike every year in the same season vetoed (an annual pattern is seasonality, not a surge). Gainers only — at least 3 qualifying stores are required to publish an edition. The best-current-discount column shows the largest plausible tracked offer at that store. Implausible percentage claims (95%+) are never shown.
