Where does a promo code actually survive checkout — Carhartt or Merrell? Instead of guessing, this page measures the two side by side on live SimplyCodes verification data: how many codes are verified working at each store right now, and the best live discount on the board. It re-checks daily, so the scoreboard below is today's answer, not last month's.
As of August 1, 2026, Carhartt comes out ahead on codes verified working — 4 to Merrell's 3. Merrell has tracked more codes over time — 482 to 116.
- Merrell has more codes tracked over time — 482 to Carhartt's 116.
- A tracked code is not a working code: the all-time tally includes expired and one-time codes, so only a small share is live at any moment — this page counts only codes verified working right now.
Codes verified working = distinct promo codes the SimplyCodes verification engine currently rates as working · Best live discount = strongest %-off among those working codes · Codes tracked = every code SimplyCodes has ever tracked at that store (context, not a working count) · Verified-working share = working ÷ tracked.

Methodology
How SimplyCodes verifies codes. Behind every figure on this page 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 run real checkout flows and record 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, where live checkout outcomes feed back into the engine. A code counts as "working" on this page only while the engine currently rates it as working at checkout.
How this comparison is built. We count, for each store, the distinct promo codes the SimplyCodes verification engine currently rates as working — codes whose current verification status is valid at checkout. That working count is the yardstick for this comparison, and both stores are measured with the same one. "Best live discount" is the strongest percent-off figure among each store's currently-working codes, read from the code's own offer text. "Codes tracked" is every code SimplyCodes has ever tracked at that store — context for scale, not a working count. When a code stops working, it drops out of the working count on the next refresh; refreshed daily.
