Wade Coggins, near Beaverton, Ore., said he finds items to sell on Amazon and eBay in store clearance sections, abandoned storage units and dumpsters. He said he has salvaged cardboard boxes, bubble wrap and peanuts from trash bins to package his orders. Blemishes need to be cleaned off, he said, adding that some people shrink-wrap items to make them look more legitimate. “When you send stuff in to Amazon,” he said, “it needs to look brand new.”
