To apply a discount code to an order, simply add the items to your cart and once at checkout, copy & paste the code into the field marked Discount Code/Gift Card. You can find this on the right side of the checkout page, just under your order summary.
Click on the ‘Apply’ button and you will see the price change accordingly.
If you have any issues with applying your discount code, please reach out to us at support@trayvax.com.
