Coupon codes can expire without notice. Each Known Supply offer on this page shows when it was last verified; codes verified within the last 30 days are most likely to work. The newest offers in our database carry expiry dates around 2026-10-01 — use them while they last, and if a code fails at checkout, check the verification date before trying again.

Buy from Known Supply's official website for the lowest price: verified codes on this page only work on the brand's own site, and official channels add subscription discounts and loyalty points. Use code KNOWN15 at checkout. Amazon wins on speed (Prime 1-2 day shipping) and easy returns, but brand coupon codes rarely apply to Amazon listings and third-party sellers often mark prices up. Rule of thumb: verified code on the official site = lowest price; Amazon = fastest delivery.

Brands release coupon codes irregularly on purpose. Most retailers avoid a predictable discount calendar because steady discounts train customers to wait for sales, which erodes profit margins. Codes typically appear for a specific purpose — clearing seasonal inventory, acquiring new customers, or a limited-time promotion — and expire when that goal is met. That is why a Known Supply code that worked last month may be gone today: it was created for a campaign window, not as a permanent offer. When a code fails at checkout, check the verification date on this page; if it is older than 30 days, look for a newer offer here instead.
