that's the long way to go about explaining it. you could also blame it on contractors trying to get uber cheap material. its been done alot, especially at new work sites. guys will hit new builds at night grabbing materials, tools, anything they can, then turn around and use them, charging people less because it didn't cost them anything.
of course if the MSM reported it, it would probably read "contractors, hit by high gas prices resort to alternative sources of building materials"
