Ditto, why buy when you have fingers?

Did you know you can also buy a special device for putting rubber bands on? Or a special devise for opening clevises - because God knows a screwdriver doesn't work well. You can even buy lead weights, cause they're cleaner than the ones you get for free at the gas station.

Bottom line - If you make it, someone will buy it.

Save your money for things that CAN be useful, like an incidence meter, or a Slot Machine, ect.
