3D3D50 pound salt block.
This 50 pound block of salt cost $4.99. That's right, 10 cents a pound retail for something once so valuable that the very word salary derives from it. In solid block form salt like this is meant for licking by cattle. It's called a salt lick and you get them at farm supply stores.
