Target discounts a selection of Mossimo Men's Fashion Socks, with prices starting from $2.78. That's the best discount we've seen on men's socks from Target. Shipping adds $4.99, or spend $50 or more to qualify for free shipping.
A best bet is the Mossimo Supply Co. Men's Taco Socks for $3 plus $4.99 for shipping. That's a buck off and the lowest total price we could find. They're available in men's size 12 to 14.
