This is like the grocery outlet of hardware stores. You can't always find exactly what you need, but there is a good selection, and if you do find something - It'll be cheap!
Unwanted paint is $5 a gallon, and you can find tools, like new building materials, very old building materials, etc. Solid interior doors start at just $10.
A must stop for anyone doing home improvements on the cheap!
Pros: Very low prices...
