I joined the PTC at my daughter's school at her Kindergarten Round Up last spring, and have become quite active as a volunteer parent. At some of our meetings, many members have asked about coupon books for our area. I grew up in New Jersey, and we had an AMAZING book through KidStuff, however they don't participate in Illinois at this time.
To make a long story short, I would LOVE to find out if there are any companies that sell similar books, or any 'custom' books (aside from Entertainment).
