Every shopping category on this board is ranked by how deep its promo-code discounts run this month, scored against that category's own year-round norm and measured from SimplyCodes verification data. The data is re-measured every day, and the month's board turns over on the first.
As of September 2, 2026, SimplyCodes measures September's deepest promo-code discounting in business, where 23.3% of verified codes run 25% off or deeper — 0.7 points above business's own year-round norm. 3 of the 17 categories measured are running above their own baselines this month.
- Business leads on lift at +0.7 points against its own norm — the measure that answers "is now a good time" rather than "is this category generous".
- Only 3 categories sit above their own baseline in September; the rest are at or below, which is the ordinary shape of a month with no major sales event in it.
- Depth alone would mislead: a category that discounts hard all year looks like a bargain every month, so every row here is measured against itself rather than against the others.
Lift = how far that category's September discounting sits above or below its own year-round norm, in percentage points · September = the share of that category's codes running 25% off or deeper this month · Year-round norm = the same share across every month on record · Retailers = how many stores contributed.

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 2.3M+ monthly code verifications 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. For every retail category we measure the share of its promo codes worth 25% off or deeper in this calendar month, and compare it against the same share across every month on record for that same category. The difference — the lift — is what the ranking is built on, because a category that discounts deeply all year round is not telling you anything about timing. Only codes whose stated value is a percentage enter the calculation, bounded between 1% and 95% to drop placeholder entries. A category appears with at least 5 contributing retailers in the month and 500 measured codes overall. One honest limit: the month figure pools every year of that calendar month on record, so it describes what this month usually looks like rather than what is happening this week. Financial-services and crypto groupings are screened out, because a page recommending what to buy should not be read as financial guidance. Figures refresh with the data snapshot shown above.
