The Treehouse is open!  Until 6/11 then installing a new payment system, probably Stripe, not sure yet if I'll have to a site overhaul.  All books $10+ have front/back scans.  Minimum order is $15 and ONE COPY LIMIT on hot books!  Checkout is via Paypal but email me at ideaman33@comcast.net if you have any probs or want to pay by Visa.
