A few weeks back I picked up a bunch of 1x10x12' culls for about $5 each. They were beautiful and once I ripped them down to 3" width I ended up with enough to frame the walls. Also picked up 4 sheets of foamboard that had a 3" hole in them for about $3 each.
Today I go back and hit what I think is the mother lode. They had a bunch more of the 1x10's, but more than that they had 2 bundles of 12' tapered cedar siding - 8" wide(cost was $10 per bundle, 6 boards per bundle). They also had, for no apparent reason, four 2x6x12' absolutely beautiful rough cut, western red cedar boards for $4.50 each. Not sure why a rough cut, absolutely straight and dry cedar would be in the "cull" bin, but it was. Even the lumber guy didn't know why it was there, but said it had been there for a couple of days. They also had several sticks of nice clear poplar of various widths. Yeah, for $140 I picked up a truck load of pretty darn good lumber.
Time to get to resawing the rest of my strips. I think I might try to turn the siding into trim boards, since I have 144 linear feet of it now.
Thank you Home Despot, you keep making this build better and cheaper all the time.
