Great if you don't have school and can work full-time. Also if you can move larger furniture if movers are not there when a shipment comes. But be wary, if you're not part of the original team, be cautious and analytical when inspecting product. Also have to be quick with inspections. If you make 3 or more mistakes, even small mistakes, they'll let you go (but if one of the originals guys can mess up deliveries and break things, it's not as big of a deal). If you have previous furniture moving experience, maybe it'll work for you.
