How to apply a code at T3

  1. 1

    Copy the code above

    Start with the one verified most recently, not the biggest number.

  2. 2

    Go to the checkout page

    Open the cart page and proceed to checkout. The promo code field is on the checkout page, not in the cart.

  3. 3

    Enter the code and apply it

    Type your code into the promo code field. Then click the apply button.

  4. 4

    Check the total dropped

    If T3 shows "Enter a valid discount code or gift card", the code did not work — tell us, and a code shoppers report as failing moves to the bottom of the list.
