Discount codes need to be entered in the coupon code field which can be found in the bottom left hand portion of the first page of checkout.
Codes are not case sensitive and will never contain spaces. If the code does not apply it may be expired or entered incorrectly. Discount codes will not apply to items on sale, gift cards and cannot be stacked (used with other discount codes).
Discount codes cannot be used in conjunction with account points but can be used alongside gift cards/store credit.
