We packed ouselves. The movers spent most of the day packing the truck. They took apart 2 cribs, moved 2 big aquariums, big screens, etc. i know we bought them subway for lunch. DH tipped them each. Just 4 guys. I can't remember how much.
We tipped them again when they moved us in. Different 4 guys. Nothing was broken, and they put together all the cribs/beds. This isn't much help I know.
We have moved a lot. This was the first time with movers. DH's job payed for it. It was sooo nice.
Oh, and it was 20% to split among a team of 3. In terms of actual numbers, I think it was around $600 (last time) but they packed and unpacked and moved us into a three story house.
