I purchased an auto service coupon on Groupon. I went to use it, but the rate the business charged was unreasonably high. So I decided to return the coupon back to Groupon and get my money back. However, their terrible return policy made it impossible to get a refund when I was not satisfied with the transaction. Apparently, their return period is three days. THREE DAYS! Who uses up their coupon/giftcard within a three-day window?! And I was not aware of this policy until I called them. Extremely displeased with Groupon and their awful return policy. One of the worst return policies I have ever encountered.
