You can apply a coupon or promo code at checkout:

1. Add your items to the cart and tap Checkout.
2. On the payment page, look for the Coupon Code & Coupons option.
3. Enter your code or select an available coupon from your account.
4. Confirm and proceed with payment.

If your code isn’t working, check if it has expired, has a minimum spend requirement, or is restricted to specific products.
