I purchased tickets on Groupon and tried to redeem when we called the venue they said one of the vouchers was already used in 2016!! Has anyone had any problems with their Groupon tickets?

I would contact Groupon, their customer service has been great to me so far. Just FYI, you should check their page before buying the Groupon, last time it was cheaper there!

I can say I have and I bought my tickets from Groupon for the pirate dinner. Okay, my suggestion call Groupon. I hsd a few problems with other tickets and Groupon costumer service fixed it. Give them a try.
