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.

Built from SimplyCodes warehouse data — every promo code copy shoppers made over the previous 30 days, grouped by where each store sits in the demand ranking. This is an all-store distribution: no individual store is named or ranked. Checked August 20, 2026 · numbers last changed August 19, 2026. Refreshed daily.
Do popular stores get most of the coupon demand?

No. As of August 19, 2026, the ten busiest stores over the previous 30 days hold 8.88% of the 9,300,943 promo code copies SimplyCodes counted, and it takes 985 stores to reach half of all coupon demand. The largest single slice, 37.55%, 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 37.55% of every code copy, 4.2× the ten busiest stores' 8.88%.
  • The head is real but shallow: the single busiest store holds 2.47% of all copies, and the top 100 stores together hold 23.81%.
  • The tail is long — 41,187 stores sit in the beyond the top 10,000 band and still account for 12.21% of demand between them, a median of 12 copies each.
  • The shape holds between windows: over the preceding 30 days the top 1,000 stores held 49.83% against 50.24% now, and half of all demand took 1,011 stores against 985.
  • Reaching nine tenths of coupon demand takes 11,691 of the 51,187 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%.

Frequently asked questions

Do popular stores get most of the coupon demand?
No. As of August 19, 2026, the ten busiest stores over the previous 30 days hold 8.88% of the 9,300,943 promo code copies SimplyCodes counted, and it takes 985 stores to reach half of all coupon demand. The largest single slice, 37.55%, belongs to stores ranked 1,001st to 10,000th.
How does SimplyCodes measure how coupon demand spreads across stores?
Every figure in the SimplyCodes Coupon Demand Concentration Study comes from SimplyCodes verification data — the engine that tests promo codes at real checkout before they are listed, through daily automated testing, a 10,000+ human verifier network, and a live checkout-outcome signal. Figures are as of August 19, 2026.
How often is SimplyCodes' data on how coupon demand spreads across stores updated?
The figures in the SimplyCodes Coupon Demand Concentration Study are as of August 19, 2026. This live data study recomputes daily. When a figure moves in SimplyCodes' verification data, it moves here on the next check.
Which SimplyCodes categories should I browse after reading about how coupon demand spreads across stores?
This live data study ranks positions in the demand curve rather than stores. The stores themselves, with the codes verified on them, sit on the SimplyCodes category pages: Clothing, Beauty, Electronics and Restaurant. Each one lists the stores SimplyCodes tracks in that category, with the codes it has verified at a real checkout.

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 0.14%, 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. Figures refresh with the data snapshot shown above.
