For those who've already made your purchase, my sincere thanks...and apologies. Lulu just sent me a promo code that would have saved you 20% off a purchase of "Crawl."
If you haven't bought a copy yet, make sure to visit Lulu.com and put in the promo code HAPPY. You can click this handy button on the right side of the screen to automatically put both the paperback and electronic editions in your cart!
(I don't know why Lulu does this, unless it's trickery to get you to buy double copies. For shame, Lulu!)
For you Kindle owners out there, "Crawl" is still available on Amazon.com for $2.99!
