canner
n.— «Eight months ago, a nonprofit organization in Midtown that served as a redemption center also closed up shop, leaving scores of Manhattan-based “canners,” as many can and bottle collectors call themselves, with no choice but to haul their unwieldy troves around the supermarket circuit.» —“Nabbing the Elusive Nickel” by Saki Knafo New York Times July 9, 2006.
