If you bought a copy previously, keep an eye on your email. We're sending out coupons for $5 off the new version, and a PDF of updated pages to previous guidebook customers. Please email [email protected] if you don't see that email in the next hour-ish.
Because there were a ton of email signups, this stock of guidebooks will likely go pretty quickly, but we've already got another print run in progress, so don't fret if it sells out. 🙇
