The Most-Shopped Coupon Categories Index

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 sum coupon-code copies across web, app, and extension over a trailing 7 days, group by shopping category, and rank the top 25. Before rolling demand up to a category, we cap copies at 6 per shopper at the merchant level to keep automated traffic out of the demand signal. Categories with too little activity to measure reliably are dropped (the measurement floor). A week-over-week figure is shown only when a category cleared 500 copies in both 7-day windows. Numbers measure demand (codes grabbed), not whether codes worked at checkout. The daily data lags about one day, so each edition is stamped "as of" the latest available data date.
