Cheap packing material

the best boxes in my opinion, ( i was the person who started the anti packing peanuts thread) are computer monitor boxes, or CPU boxes...they are usually triple walled....total overkill....so....you could check behind the CompUSA and find some gems

I agree with Justlisten. When we get new computer monitors at work, they always put the boxes out by the dumster. They immediately go in my car when I see them. They really are strong.

Sears is good for large boxes, my local Sears outlet will let me come down in the morning 1st thing and pick out what I want. Places that sell large office copiers usually have great boxes as well. Foam 4x8 1/2 or 3/4 thick sheets are available from Home Depot or the like. Cut easy with a razor knife, and with tape you can make about any kind of foam support you need.

One day come with the car or truck to PC Richard's, Toys'R'Us or any major store and ask for boxes. You're not going to imagine how many you can get of a different sizes.
Besides, you can tear some of them to have extra carton for dividing components or fortifying the box. So the only probably thing that left for you to buy is the bubblewrap that you can get cheaper at the truck rentals office or Home Depot rather than in Staple's.
