Ain't it funny how the raw potatoes dug out of the ground are just as cheap as they were 5 years ago here in my state, while potato chips have doubled in price?

Ain't it funny how the raw potatoes dug out of the ground are just as cheap as they were 5 years ago here in my state, while potato chips have doubled in price?
