Methodology
How SimplyCodes verifies codes. Behind every figure on this page 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 real checkout flows and record whether a discount actually applies; a human verification network of 10,000+ verifiers submitting 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 group every pet supplies promo code SimplyCodes has checked at the pet retailers SimplyCodes tracks by the calendar month it was verified in — so "December" means every December on record, not one year's. For each month we report the share of those codes that carried a discount of 25% off or deeper, alongside the number of codes behind the share. 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
