A member must be logged into their account to redeem points. Points can redeemed during the checkout process for one-time products. If you are attempting to add a discount to a recurring subscription order please see: "How to apply a discount code to a subscription order".
Once you reach the checkout screen you will see your total available Rewards points. To use your rewards, select your redemption amount using the dropdown menu, then continue with the checkout process. Remember you must have a minimum balance of at least 100 points each time you want to make a redemption.
