I’ve added a PayPal button to the book website
so that readers can now order a signed copy of the book online, using
PayPal. If I’ve implemented it correctly, it should work. There is a
entry box so a customer can ask for a specific message in the signature.
Now, to see if it works. There is also the option of sending checks or money orders. Sorry it took so long to implement this, I need to clone myself.
