You may be able to copy and paste the code from your voucher to the website coupon box to ensure accuracy.
Also, please be sure that you are using the redemption code listed and NOT the voucher’s order number. If you need help finding or confirming your redemption code please check out Groupon's FAQ page for troubleshooting information.
