Excerpt:
"Decluttr takes advantage of that gap. The reason it buys everything is simple, Lauter says: “The first CD you scan in may be another Jagged Little Pill. If we say we’re not going to buy it, you may give up. We just lost you. So we’re going to give you the minimum, 50 cents, because maybe your second one is Green Day’s Insomniac, and oh my gosh, this will sell quickly.” In fact, that 1995 album is one of the hottest on the market now; Decluttr currently pays people $5 for it. “It would be poor judgment on our part if we’d blown you off on your first CD.”
