I learned a long time ago, if it says "gun" on it you can probably get something similar at Home Depot for about 1/3 the cost. I polish the furniture with Carnauba floor wax. A half gallon tin runs about the same prices as Casey's 3 oz. bottle of "stock wax" -- and it's better wax.
Have a look at contractor tools, boxes, etc. They basically have the same sorts of needs, only they're out to make a buck, not keep a gun shop in the black.
