When you have found your favourite pair of glasses, you can order them by clicking on the yellow 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 the option to check out as a guest. During Step 5 in the check out process, you will find payment options. Simply choose “Do you have a gift card from Ace & Tate?” and fill in your gift card code. The gift card amount will then be deducted from the price of your order.
