Macy’s offers the Martha Stewart Essentials 12-Piece Glassware Set in an assortment of styles and sizes for $17.99. Coupon code “FRIEND” cuts that price to $12.59. Opt for in-store pickup to avoid the $9.95 shipping fee. That’s $17 off and the lowest price we could find, although we saw these for $3 less last week. Choose from tumblers, flutes, and wine glasses. Deal ends May 5.
