Printed copies of the IFAF tackle rulebook
Printed copies of the IFAF tackle rulebook are available through a print-on-demand service called lulu.com. The book comes with a handy coil binding so that it opens easily.
Print-on-demand means that the book will be printed somewhere near your part of the world and shipped to you. This usually takes just a few days.
Lulu offers good discounts if you order in bulk (e.g. on behalf of your officials association). You can often also get a discount by using a coupon code, obtainable from https://www.lulu.com/home
