How we cover business.
Every business coupon on 99 Coupons goes through the same four checks: an automated cart simulator applies the code at the merchant's checkout, AI cross-references the discount against published terms, a human editor reviews edge cases, and community signals flag anything that breaks after publication. The whole cycle runs every 24 hours.
If a code stops working twice in a row, it disappears the same day. No expired-coupon graveyards, no "click to reveal" theatre on dead offers.
