It seems like you have three options for your outstanding groupon vouchers if you can't use them:

Option 1: If you prefer to use this deal at a later date, we are in the process of extending all voucher expiration dates by one year. You can expect a follow-up email with more information about your voucher’s expiration date (if you don’t hear from us by the end of the month, please reach out again and we’ll provide an update).

Option 2: Or, I can cancel your order and process a refund in Groupon Credit, which can be used toward future purchases. In addition, we’ll also apply 10% of the refunded amount toward your next Groupon purchase.

Option 3: They can refund back on your credit card.

Can be processed through a live chat.
