When you have found your favourite pair of glasses, you can order them by clicking on the blue button "add to cart". From there you can select "place order" and log in if you already have an Ace & Tate account. If you do not have an account yet, you can choose for the option "I am new at Ace & Tate". After you have filled in all your information, you can fill in the gift card code on the right side of the checkout screen and click on "Activate". The gift card will now be deducted from the price of your order.
