How to use a promo code
Updated October 12, 2026
Deals with a promo code show a CODE label on the deal card.
Using the code
- Open the deal and tap Reveal code & open store.
- The code is copied for you, and the store opens in a new tab.
- Add the product to your cart, then paste the code into the store's promo code, coupon or discount box at checkout.
If the code doesn't copy, it's still shown on the deal page. Type it in exactly as shown.
Member-only codes
Some codes are only for GreenTechPlus members. Sign in to see them; it's free. See How to unlock member exclusives. Member codes are often one use per customer.
If the code doesn't work
Check these first:
- Spelling. No extra spaces before or after the code.
- The right product. Some codes only work on certain products, sizes or colors.
- The rules. Some codes need a minimum order, only work on a first order, or can't be combined with a sale price or another code. The deal page's The catch section lists any rules we know about.
- A US address. Codes are for US storefronts and usually need a US shipping address.
Still not working? The code may have stopped working since we checked. Please report it, and tell us any message the store showed. We remove codes that no longer work.
