Target offers the CorningWare French 10-Piece Bake Set in White, bundled with a $20 Target Gift Card, for $49.99. Pad your order to over $50 and apply coupon code "TGRDZRHP" to cut that to $44.99 (excluding padding). With free shipping, that's the lowest total price we could find by $15. It includes a 1.5-qt. oval dish with cover, 15-oz. oval dish, 2.5-qt. oval dish with cover, baking dish, and ramekins. Deal ends May 7.
Of note, we saw a CorningWare 6-Piece Bakeware Set for $19.99 with pickup at JCPenney yesterday, as listed here.
