Last night, as I was lying down to sleep, an idea came to me. If amazon.com made a deal with Good Will of some company like that, they could have a win-win-win-win situation. Here's my idea: people who donate their paperback books, get credits toward electronic books for their Kindle. The homeless will have access to literature at discount prices, Good Will will make some money off the books, the donator gets ebooks and amazon.com gets people buying Kindles and shopping at amazon.com.
