Frequently asked questions
Which retailer added the most promo codes October 2026?
As of November 4, 2026, Newegg added the most, moving from 8 tracked promo codes to 63 — a gain of 55 against September 2026.
How does SimplyCodes measure which retailers are adding promo codes?
SimplyCodes counts the distinct promo codes it tracks at each store and compares the current period against September 2026. Codes are tested at real checkout before they are listed, so a rise means a store genuinely put more codes into circulation rather than that more codes were scraped. Checked November 4, 2026.
How often do these retailer promo code movements update?
Daily. The comparison re-runs against SimplyCodes verification data every day and re-states itself, with the check date printed at the top.
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 run through real checkout flows and record whether a discount actually applies. A human verification network of 10,000+ verifiers submitting screenshot-and-timestamp proof, at 2.3M+ monthly code verifications and 98% accuracy. And a real-time fleet signal feeds live checkout outcomes back into the engine. A code counts in this live data study while it is tracked in SimplyCodes verification data.
How this radar is built. We compare each store's monthly summary of tracked promo codes in SimplyCodes verification data across the two most recent months with data (September 2026 vs October 2026). A store makes the board when it added tracked codes month over month, carries at least 3 tracked codes, and draws real shopper search demand. Data-quality outliers are excluded: stores with implausible code inflation are dropped before ranking, and implausible discount claims (percentage discounts of 95% or higher) are never shown as a store's best discount. Stores are ranked by codes added. The best-current-discount column shows the largest discount among the store's tracked codes this month. Month-over-month figures update as new monthly summaries land.
