An implausibly deep discount claim is easy to type and rarely real — so this board earns its numbers. It ranks recognizable stores by the deepest percent-off coupon tracked over the trailing 30 days, throws out implausible claims (95%+ percentage offers are feed noise, not deals), and only names a store when it also has 3+ codes currently verified working at checkout. When the deep offer cools, the "this week" column shows it first.
As of August 15, 2026, the deepest discount among recognizable stores on SimplyCodes is 85% off at GOG, tracked within the trailing 30 days.
- SnapFish (75% off) and J. Crew Factory (70% off) round out the top three.
- Every store named carries 3+ codes currently verified working — a deep headline discount only makes the board at a store whose codes actually check out.
- The "this week" column shows the deepest percent-off tracked in the trailing 7 days — when it lags the 30-day figure, the deepest offer has cooled.
Deepest % off (30d) = the largest percent-off coupon tracked at that store in the trailing 30 days · This week = the same measure over the trailing 7 days (— = none tracked this week) · Verified working codes = distinct codes currently verified working (Health Score ≥ 67).

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 runs headless browsers through real checkout flows and records whether a discount actually applies. A human verification network of 10,000+ verifiers submits screenshot-and-timestamp proof, at 4.6M+ verification actions a month and 98% accuracy. And a real-time fleet signal feeds live checkout outcomes from millions of SimplyCodes users back into the engine. Each code carries a Health Score from 0–100, weighted by checkout outcomes, verifier consensus, and recency. With an estimated 40–60% of coupon codes on the public web dead, restricted, or fake, the system exists so a code earns its place by working at checkout, not by being collected.
How this study is built. We take, for each store, the deepest percent-off coupon tracked over the trailing 30 days and rank recognizable stores by that figure (ties broken by demand). A store is named only when it also has 3 or more codes currently verified working (Health Score 67 or higher) — so a deep discount claim is always backed by a board of codes that actually check out. Percentage claims of 95% or higher are implausible feed noise and never publish (the same plausibility gate the SimplyCodes sale calendars use), and stores with implausible code inflation (more than 500 codes in a month) are dropped. A tracked discount is the offer's declared depth, not a per-checkout guarantee — the verified-codes column carries the verification read. Figures refresh with the data snapshot shown above.
