**Update** Groupon has updated the wording on this and it appears to only be valid at 2 locations in Michigan. There is a 3 day refund period on these vouchers so you will want to login to your Groupon account and request a refund. I apologize for the confusion, I carefully read the wording before posting and it had been updated since my post.
