Weber’s Book of Grilled Pizza

[Farace]

Looking forward to grilling some pizza (or as we say in the greater New Haven area, apizza) this coming weekend and I dug out my copy of Weber's Book of Grilled Pizza. I Googled it just for kicks, and found it's selling on Amazon for $15 new (plus $4.62 shipping) or $8 used (plus $4 shipping), which kind of surprised me. Back when I got this in 2001, Weber was sending them out for free, just for the asking. Has this become a collector's item or something? It's sure not a $15 book.
