When you find the Altrec coupon code you want to use, just click on the provided link, shop at the merchant's site as you normally would and then enter the provided "coupon code" during checkout. If a "coupon code" is not provided, your savings will be automatically applied to your order. However, it is always a good idea to verify that your discount has been applied before finalizing your order. Tip: When clicking a coupon link, you'll be taken to the merchant's site without seeing a traditional coupon. Please ensure your savings are applied before completing the order.
