A method of dispensing sheet material from two rolls includes dispensing a first sheet of material from a first roll of the material located at a first location, lowering the first roll from the first location as the first sheet of material is being dispensed, lowering a second roll of material onto a second location above the first location when the first roll has been lowered to a location below the first location, and dispensing a second sheet of material from the second roll. A dispenser allowing for dispensing from two rolls includes a first wall having a forward end, a second wall opposite and spaced apart from the first wall and a cam coupled to each wall.
