When moving valuable items, keep the movers happy. On our last move, we intimated the amount of the tip early in the moving process, as the moving crew was packing everything up.
Depending on the complexity of the move, we believe that a tip of $25 for each mover and $75 for the crew chief is a good rule of thumb if they do a great job. (That means no breakage and they set up the mattress frames.)
