WHY FAIRPERK
Everything you want from a coupon extension. Nothing you don’t.
Attribution stays intact
FAIRPERK does not rewrite affiliate links, add affiliate parameters, or touch affiliate cookies.
Better code confidence
Coupon results help rank codes by real-world reliability, so the best options appear first.
THE FAIRPERK PROMISE
Simple enough to trust.
Our safeguards are intentionally narrow and easy to verify. If we cannot safely test codes on a checkout, we switch to manual copy instead.
