I don't know how I possibly would have gotten through my recent house remodeling if it weren't for J-A-R Supply. They carry anything that you could possibly need to finish any home plumbing or heating project, from a small repair, to a major renovation or build. While they supply mostly contractors, big and small, any do-it-yourselfer who can find the big brick building that is set far back from the road (State St.), can supply their project there.
If they don't have it, they can get it. Literally one-stop shopping.
