If you are like me and have Groupon vouchers that you bought before all this chaos, it looks like Groupon will be extending expiration dates for up to 12 months. In addition, if you’d rather trade in your voucher for something else or want it refunded in the form of Groupon Bucks, their rep can issue the refund for you. I hope this helps.
