How We Verify Grown Brilliance Codes
Nothing goes up here on trust. A Grown Brilliance code is collected, applied to a real grownbrilliance.com cart, dated the last time it took money off an order, scored on what came back, and pulled once it stops clearing. Promotions have no code to run through a checkout, so those are dated when they go live and dropped when they lapse. Here is how far that has got on this page, and every change the agents logged along the way.
