A best bet is the Lynx Men's Flat Front Shorts in Black (pictured), Stone, or Khaki for $24.97 before the above coupon, $12.48 after. With $6.99 for shipping, that's $38 off and the lowest total price we could find for this style. It's available in sizes 30 to 42, although not in all size/color combinations.
Meanwhile, Golfsmith also takes an extra 50% off clearance items. It does not stack with the coupon above.
