ALBANY, CA—Applying tape to the last package in a 12-item round of eBay sales, Brandon Vye scanned his bedroom for anything else he could auction off online. "I sold the Grand Ole Opry floaty pen... the UNO cards... the Santa socks—so now what?" Vye asked as he spun around in his swivel chair. "Maybe I could sell these science textbooks, or my tapes of old SNL episodes? God, I've got to have something I can mail off."After listing a misshapen clay bowl he made in a high-school ceramics class, Vye decided to head out to the yard to search for "eBay-able stuff" there.
