The large paper bags of sugar in the baking aisle on the bottom shelves are all granulated...
Up on the shelves, there is also a superfine (castor) sugar that's usually in a smaller canister or plastic bag that's used when you need a faster dissolve time. Other sugars, which will be in boxes, cartons, or plastic bags are, confectioners, glazing (confectioners without the cornstarch), cubes, rock, decorative (large or regular grain crystals for topping baked goods, usually colored--the large chunky non-colored crystals are particularly wonderful sprinkled on top of pie crusts before baking), sugar cones, kluentje (a large chunk German tea sugar related to rock sugar) and others.
