Scalable Planning (ScalPL) Book Price Reduced

I figure the early early adopters have had their chance, so I've reduced the price of my book, "Scalable Planning: Concurrent Action from Elemental Thinking," from $65 to $45 for the later early adopters!  And if you use the 20% discount code available at elepar.com (before it goes away), that's actually more like $36 -- about half the original price.  Plenty more info about the book on this blog and at the elepar website.  Questions and feedback are welcome.
