I only buy the book when it is very cheap. Since I had head/neck surgery in Dec 2011, I am unable to eat/drink in the traditional way. The requirement that the coupons are 2 for 1 meals do my wife little good. Worse, there have been more coupons where 2 beverages also have to be purchased in addition to the paid meal.
Also, some of the restaurants seem to be out of business with the bad economy.
