Another source for inexpensive materials

My wife was reading a local newspaper and saw an advertisement that a new Habitat for Humanity Restore is coming to Columbia, MD.  Given that's where our garden plot is, that'll be convenient to find more reasonably-priced reclaimed building materials.  While I love The Forklift, there are a few downsides to it:

• It's closed on Mondays.
• Hardware (screws, nuts, bolts, etc) often comes in undesirable sizes or is rusty.
• Going to The Forklift requires a bit more planning for travel times.  It's a lot farther away from the house than the plot.

I'll still frequent The Forklift, but it'll be nice to have an alternative source when I'm starting from home.
