It's not hard to find, any grocery store has it in the pre-cut aisle, but usually the pre-cut ones are kind of waxy and not nearly as fresh and tasty as having it sliced at the counter. Some grocery stores have it at the deli counter to be sliced. It's pretty pricey though, can be up to $25 a pound, but you wouldn't really need a whole lot of it.
Good for charcuterie boards with crackers and olives and cheese etc, or put a couple slices in your sandwiches.
