Was at a charity golf event today and they were doing a fundraiser selling these discount cards that cost $29/month. The card came with multiple discounts, % off movies theaters, dinning, shopping, airline tix, etc. which is cool. It reminded me of the old "entertainment books" but what got me is they give you a $50 restaurant.com certificate every month. For me that was no brainer, $29 for $50 certificate + the other perks and discounts. But how is restaurant.com? any good or bad experiences using them?
