You earn at least 1 point for every $1 you spend on qualified purchases (depending on whether you’re a “light,” “moderate,” or “super” Rewards member) — excluding discounts, returns, taxes, and fees. You can also earn points by completing the actions described on the Thinx Rewards page. There is no limit to how many points you can earn, just make sure you check out using the same email you used to sign up.
