How does SimplyCodes know when beauty products discounts run deepest?
Every figure comes from SimplyCodes verification data: promo codes are tested at real checkout before they are listed, and the discount each one actually delivered is recorded with the month it ran. The beauty products calendar reads those records back month by month, so it reports discounts that were measured, not discounts that were advertised. Checked August 21, 2026.
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, where headless browsers 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. And a real-time fleet signal, where live checkout outcomes feed back into the engine. The calendar below summarizes that verification history month by month.
How this calendar is built. we take every beauty products store SimplyCodes tracks at the beauty retailers SimplyCodes tracks and record, for each calendar month that store ran a percentage-off code, the deepest discount it offered that month — so "December" means every December on record, not one year's. For each month we report the share of those stores whose deepest code reached 25% off or more, alongside the number of store-months behind the share. This measures how many stores discount deeply in a given month, not how many individual codes did. Only percentage-off codes are counted, because fixed-amount offers are not comparable across price points. Percentage claims of 95% or more are excluded as implausible. And a month contributed by fewer than 3 retailers publishes no share at all
