I've been mulling a way to sell autographed copies of my books. Ordering off Amazon will get you a print copy, but my signature won't be a part of it. So, in the near future I will experiment with a Paypal button. What I have to figure out is how potential buyers can let me know what to write on the inside--unless my name is sufficient. Also, shipping methods and costs are something to consider. Of course, I will let you know when and if I get it set up.
Be good to yourselves!
