Signed paperback copies of all US editions are available for list price plus shipping & handling; they can be personalized if you wish. (I will ship books internationally, but the cost of postage to locations outside of the US is out of my control.) Signed bookplates are also available (and currently on sale!). They’re 3x4 inches and adhesive-backed.
Payments are handled by your choice of Paypal or Stripe, which accepts Visa, Mastercard, AMEX, Discover, and Apple Pay. Please allow 4-6 weeks for shipping within the US, longer for international shipments. (I try to ship books out within 1-2 weeks of receiving an order, but I keep limited stock on hand and sometimes have to order them.)
