For those of you that make stuff -- automata or otherwise -- Northern Tool is running a special promotion where you get a gift card with your purchase. Type in this promo code on the Address Verification page: 94660.
The offer applies to orders over $100 bucks, but this time of year, that's easy to do. They have pretty much every tool under the sun from a $2 strap wrench to a bulldozer that goes for $21,800!
Don't take my word for it...see if there is a tool you cannot find at Northern Tool + Equipment.
(If are unable to find a tool, post it as a comment here.)
