But if you're moving on your own dime and all your extra dimes have gone into that down payment or are being set aside for a pool at the new house, there are ways to cut costs:
BYOB
Shop around and you can usually find a deal on your own boxes. Get them in all sizes and remember that certain boxes are designed for certain purposes. Putting clothing in a flat-screen TV box is a waste of space, spring for the garment boxes.
And don't make the mistake of thinking you can bring home and use boxes from work. They've already been stressed with something heavy. Do you really want to get them to the breaking point when you fill them with your dishware?
Staging Area
Moving guys are on the clock when they arrive and you sign the contract, so the easier you make it for them the faster they can be done. Use your garage or a central room as a staging area to store boxes that are full, labeled and ready to be loaded on the truck.
Sure About the Insurance?
You may be asked about whether you want to buy extra insurance to cover your items if they're damaged in the move.
Movers by law provide a basic "valuation" up to a predetermined limit. If you're asking them to move a couple of 42-inch LCDs, your home entertainment system and a grandfather clock made by your grandfather, it may be worth it to buy the extra coverage. If you're not moving anything too valuable, ask for the company's valuation limit and go from there.
