When we went to Hawaii we ordered the one for Hawaii before we went. We knew we were going to lots of the places that were offered so we got our money back and a bit. Normally, it's not that great of a deal for us as we don't eat out much, but that being said, we do rent cars and the coupons for car rentals are great! It's also fun to pass on the coupons we don't need to others!
If you can't see yourself recovering your $20.11. You could wait until Spring when they go on for $10, usually May. Or wait until July when they usually go 2/$10!
