This guide comes completely free with its respective curriculum kit. However, at your insistence, we've made them available for purchase by phone as well. Please note that due to the proprietary nature of these books, they are non-returnable. (If you have any questions about the contents, please don't hesitate to inquire before you purchase this non-returnable item!) Each handbook purchased comes with a certificate for $25 off your next Timberdoodle Curriculum Kit (excludes free handbooks included in kits). These certificates are only redeemable by phone, but are valid for any kit - Basic, Complete, Elite, or Custom.
