I am looking for candy cherries to make fruit cake. Who has them.

Walmart ot Winco

Winco, Smith's

Are mascherino cherries the same as candy cherries?

I have always wondered who actually likes fruitcake.

Ray is dead on. You'll likely find a place to sell them to you, similarly you can find places to sell you candy corn. And like candy corn, nobody should buy candy cherries or fruit cake.
