How vendors are rated and coupons are verified
Vendor ratings
A 0-10 score on four published factors
COA practices carry 40% of the score: a named third-party laboratory, batch linkage, public reports, testing breadth and independent verifiability. Community reputation, transparency and operations carry 20% each. Affiliate status has zero weight, and each vendor profile shows the date it was last updated.
Coupon verification
Every code carries its check date
Every offer in the hub was checked on November 6, 2026. An offer is labeled verified only when its code, discount and offer link match a recorded check, and a changed or new offer needs its own check before it carries the label. Each vendor's coupon page states the code, the discount and the date it was last checked.
