Is your order for $175 or more? That may be the problem — coupon codes are only valid for orders of at least $175.
You may also want to check the order minimum requirement for the coupon that you have, as some of our coupons have a minimum purchase requirement of $225.
If your referral coupon code isn't working, it may be sent from the same household or the same IP address. Our referral coupon codes are limited to one per household.
If it still isn't working, please live chat us or email us at firstname.lastname@example.org.
