A monopolistic seller is marketing a good to a customer whose willingness to pay is determined by both his private type and the quality of the good. The seller can design a menu of both prices and experiments --- that reveal information about quality. We show that the optimal mechanism features both price discrimination and information discrimination: buyers with higher private types face lower prices and receive less precise positive signals. Our mechanism remains optimal within a general class of mechanisms satisfying ex post individually rationality. Overall, information design facilitates surplus creation (destruction) on the extensive (intensive) margin.
