Walmart discounts a selection of men's, women's, and kids' shorts, with prices starting at $2. Opt for in-store pickup to avoid shipping charges which start at $4.97, or spend $50 or more to score free shipping. A couple of best bets:
Target via eBay offers the Mossimo Supply Co. Men's Belted Flat Front Shorts in nine colors (Oxford Blue pictured) for $14.99 with free shipping. That's a savings of $5 and the lowest total price we could find. They're available in sizes 26 to 44, although not in all size/color combinations.
Boden offers its Boden Men's Poolside Shorts in Orange Spot (pictured) or Bright Blue for $32.40 plus $10 for shipping. That's $22 off list price and the lowest total price we could find. They're available in sizes 30 to 44, although not in all color/size combinations.
