When moving, it is always best to ask a place such as Wal Mart, or Superstore to save some of their boxes after they stock their shelves. WalMart goes through hundreds of boxes (per store) every single night when filling the shelves, so they are a brilliant route to go as they would have plenty of boxes of any shape, size or color. All empty boxes WalMart has goes into a compact device so they can ship the flattened boxes away, so any boxes given away to customers saves WalMart money as they don't have to compact near as much.
