All of the 2016 version Study Guides have now been removed from the iTunes / iBooks store, and have been replaced with the upgraded 2017 editions. If you purchased a 2016 book during December of 2016, you did not gain the advantage of updates on this book. In the interest of fairness, if you purchased a 2016 book in the last month of the calendar year, I will upgrade that purchase to a 2017 book.
I have no insight into who the purchasers are, so if you are in that category and want to take advantage of this offer, please email me using the contact form below. Just send me a copy of your receipt and I will send you an upgrade voucher.
Thanks for your continued support of these guides!
