One Tuesday, an alert pinged: “Lot of 500: Assorted Art & Architecture – Condition: Like New.” The price was suspiciously low, likely a bookstore in Des Moines closing its doors and dumping inventory into an Amazon fulfillment center just to stop the bleeding. Arthur hit "Buy Now" before his brain could process the shipping logistics.

Arthur spent the night "mining." He tore through the tape, finding the usual filler—outdated travel guides and coffee table books about cats. But then, near the bottom of the fourteenth box, he found it: a pristine, shrink-wrapped copy of a limited-edition . He checked the current market value. It was worth more than the entire 500-book lot combined.

By Friday, Arthur had flipped the rare finds to specialized collectors and donated the "filler" to a local literacy program for a tax write-off. He sat in his suddenly spacious apartment, sipping tea, and watched his seller dashboard tick upward.
