Here's something that allowed this whole "buying books online" thing to hit home for me. I had to pick up three books for a summer college class, and "With Amusement For All" was one of them. I went on Amazon.com and blindly picked up a hardcover copy, and, when it arrived, I noticed that it had been picked, packed, and shipped from Seattle's Goodwill Industries.
Buying this book, and knowing that whatever I paid for it, went to Goodwill, makes me feel better about buying it. That's the magic of the Internet.
