Autographed books will ship as soon as I receive them for autographing. The additional price is to cover extra shipping and handling charges.
A digital version be be released later this year with updates and corrections. If you buy the hardback book before then from this site, you will receive a coupon for 50% off the digital version. A digital version is very handy with clickable links in the table of contents. I've been using it a lot while proofing and it's been easy to use.
Other digital products are planned such as a Toothaker family tree. These will be up to date family trees - not necessarily all vetted but all the information I have that may assist you in your research.
