There is a company in Calgary that sells containers for less than scrap price.
They have tried cutting the sides out and selling them as chip stands even.
The problem for scrap yards with containers is they cost too much to cut or crush as scrap, are too big for garden sheds and too heavy for people to drag around.
Ranchers here buy them just to store farm machinery in.

If you shop around a bit you should be able to find them a lot cheaper.
