You can redeem a coupon or gift code on the Redeem Gift page of your account. This page is located in the icon drop down at the top right. Your coupon will automatically apply to your next scheduled delivery (only one coupon code can be added to an order).
To confirm the coupon has been applied, it can be viewed on your Upcoming Deliveries page by clicking Order Details for a specific week. It can also be viewed via your cart on the Change Meals page.
You can view any remaining gift credit values on your My Account page under Payment Information.
Please note: coupon totals will display in the order details drop down on your Upcoming Deliveries page one week in advance.
