As a not-so-handy lady who is often sent on office errands, this is my go to place. There are a bunch of awesome young men and one old wizard who will go back into the Jacob's Hardware abyss and come out with whatever you asked for: a screw, a level, a ladder, lumber, paint, or any made-to-measure doohickey under the sun!
Go to here. It is good.
