Inside Forever Young's trove are more than 250,000 items including vinyl, CDs, cassettes, T-shirts, record players and collectibles. It's also where owner David Eckstrom evaluates potential buys from 10 a.m. to 1 p.m. every Monday, Wednesday and Friday. He says collectability, sellability and condition are key factors for sellers seeking top dollar for their merchandise. "Condition falls more heavily on value for Elvis and the Beatles and the like," he says. "Otherwise, I'll buy [practically] anything in good shape because somebody will value it. If I don't have it, and they come in looking for it, I can't sell it them."
