I had the chance to make it out to the iconic Strand bookstore in NY last week and launched a search for PNI. I found two review copies in the Reviewer section of the store … a place where they sell the review copies that the store gets for 50% off of retail. So PNI was selling there at Strand for about $12 - definitely the cheapest I have seen it for sale so far. There were only two copies left when I was there a few days ago, so if you want to save a few bucks and live in NY you better get there fast!
