I've had some emails about the fact that people can't access the Buy the Book
page on my website on Saturday, for my Birthday Special price of $39.95
This is because, as an observant Jew, I don't want to sell things on the Sabbath. A piece of rather clever software knows from where you are accessing the page and between Sunset on Friday and nightfall on Saturday night - in the place where you live - it won't let you access this page. The rest of the site, however, is open.
Apologies for any inconvenience caused, but there are still six other days in the week, and I like to withdraw to a world of spirituality on Shabbat.
