All these woodworking and tool catalogs are free to order!
Even if you usually order online, it's still nice to receive something in the mail that you are interested in looking at. It's like eye candy for woodworkers.

Lee Valley Has two very good catalogs for woodworkers, a hardware and a hand tool catalog.
