Cheap building materials you say?

In my never-ending quest for the right fittings for my reclaimed-materials bookcase, I traveled to my local Habitat for Humanity Restore, a veritable treasure trove of stuff I shouldn't be thinking about buying because I don't really at this moment have a use for it. Windows and doors, plumbing fixtures, contractor remainders of all types - it's a great place to pick up cut-rate materials, although you can never be sure what will be in stock. I left with four 4x4 beams (non pressure treated) at $2/piece. Worth checking out the one in your area.
