Well, now we know:

Ya know, I'm kind of disappointed. I had hoped that maybe the first group of autograph seekers really were fans of my books but alas, no, they weren't. I'm also glad I didn't send anything to anyone else who emailed me - not because they would have sold the items on eBay but because they would have saturated the market and my autograph would be worth less than the 1 euro it's selling for here.
LOL!!!!!!!!!!!!!!!!!!
1 euro.
Saturated market.
Please.
