Check out Macy's Summer Sandal Sale, ending July 10. You can find a variety of styles with prices starting at just $14.75 (originally $29.50 or more). Some of my favorite deals include designer sandals for $57 (originally $95) and Tommy Hilfiger sandals for $39 (originally $65). No promo codes are needed — just great deals.
