I tried to use previously purchased Groupons to buy tickets, but was not able to redeem them. Then I had to pay a service charge of $1.25 per ticket, so it cost me $7.50 for the inconvenience of buying tickets through this site. If I had not been given a couple of these giftcards, I never would have used this site. Also, I still need to go to the box office to get my tickets. Total waste of time.
