Why do you need to print it until you know that you will use it? I buy just in case and keep it unprinted until I decide.
All I'm saying is if that's the clause then it diminishes the offering of the "Anytime" refunds. Let's say I was hoping to go out with friends and use a Groupon coupon, so I print it out. Then we decide to go somewhere else. I can no longer get an "anytime refund".
They revised/removed the Groupon Promise so that:
A. they could start charging for Groupon VIP (which includes a similar feature).
B. They no longer offer a cash refund, now they just have to give you Groupon Bucks, which cost them less than giving you a cash refund.
