Macy's offers the Nike Men's Dri-Fit Swoosh Tennis Polo Shirt in nine colors for $21.99. In-cart, it falls to $15.39 and coupon code "SAVE" drops it to $13.08. With $9.95 for shipping, that's $12 under the lowest total price we could find for a comparable Nike Dri-Fit polo shirt elsewhere. It's available in sizes S to XXL, although not in all size/color combinations. Deal ends January 12.
