To check out the Print On Demand version of The Portal, I placed an order for it from Amazon on Saturday, with my two-day Amazon Prime shipping. It arrived today, Wednesday. So they were able to print the book on Sunday (I guess) and ship it to me on Monday. And it looks great!
I’m going to buy a bunch for my own use direct from the publisher. I should be able to undercut Amazon’s prices significantly, although I don’t know about two-day shipping. If you’re interested in buying one from me, let me know in comments or somewhere. The advantage to buying it directly from me, in addition to the price, is that you can get my autograph in it. Which is, of course, priceless.
