This live data study measures how coupon demand spreads across stores, counting every promo code copy shoppers made on SimplyCodes over the previous thirty days. The board below reports what share of those copies the busiest stores hold against the long tail beneath them, and the whole curve is rebuilt daily.
No. As of September 8, 2026, the ten busiest stores over the previous 30 days hold 8.80% of the 9,532,749 promo code copies SimplyCodes counted, and it takes 956 stores to reach half of all coupon demand. The largest single slice, 36.85%, belongs to stores ranked 1,001st to 10,000th.
- Stores ranked 1,001st to 10,000th are the largest single band on the board — 9,000 stores holding 36.85% of every code copy, 4.2× the ten busiest stores' 8.80%.
- The head is real but shallow: the single busiest store holds 2.23% of all copies, and the top 100 stores together hold 23.41%.
- The tail is long — 42,469 stores sit in the beyond the top 10,000 band and still account for 12.47% of demand between them, a median of 13 copies each.
- The shape holds between windows: over the preceding 30 days the top 1,000 stores held 50.25% against 50.68% now, and half of all demand took 984 stores against 956.
- Reaching nine tenths of coupon demand takes 11,961 of the 52,469 stores shoppers copied a code for at all.
Share of demand = that band's share of every code copy counted · Stores = how many stores sit in the band · Code copies = the copies behind the share · Typical store = the median copies a store in that band drew. Bands do not overlap, so the shares add to 100%.

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. We count every promo code copy on SimplyCodes over the previous 30 complete days of data, group the copies by store, rank the stores from busiest to quietest, and report what share of all copies each band of that ranking holds. This is SimplyCodes' own shopper demand rather than the whole web's: it describes where the people who use SimplyCodes look for codes, which is the demand a code-verification service can observe directly. Automated copying is capped rather than counted — a store averaging more than six copies per distinct shopper is held to six per shopper before the shares are computed, and on this window that cap moves the total by 0.35%, so the curve is not a product of it. Stores in medications and treatments, gambling, and hunting, archery and self-defence are excluded by category before counting, and stores we hold no retail category for are kept, because dropping them would empty the very tail this study measures. Bands are positions in the ranking, so the board is a ladder rather than a league table: no individual store is named, ranked or graded anywhere on it.
