I recently bought several Groupons for meal delivery subscription services. They've each been impossible to use, and I've followed the instructions to the letter. In every instance, something has gone wrong and I haven't been able to use the voucher. So far, I've eventually able to get it resolved but it's taken a lot of time and I'm Not done sorting it out. At first I was able to communicate with a Groupon representative via e-mail, but they got rid of it. Now you have to communicate via a form which is virtually impossible. Not worth it and there are better ways of getting discounts. I won't buy Groupons again.
