Signed, personalized (if you wish) paperback copies of all US editions are available for list price plus shipping & handling. (Note: Books will ship internationally, but the cost of postage to locations outside of the US is rather high, and unfortunately that is out of my control.)
Signed, adhesive bookplates are 3x4 inches, ship anywhere, and make a good alternative to having a signed book shipped internationally. (Unsigned books are available from all major book chains and distributors, including Book Depository, which ships globally.)
Payments are handled by your choice of Paypal or the worldwide web transaction provider Stripe, which accepts Mastercard, Visa, AMEX, Discover, and Apple Pay. Please allow 4-6 weeks for shipping within the US, and longer for international shipments.
