Foot Locker offers Six Pairs of Nike Men's or Women's Socks in Black or White in 25 different styles for $19.99 with free shipping. (Add two 3-packs to your cart to get this price.) That's $3.33/pair, tied with our September mention, and the lowest total price we could find for most of these socks by at least $4. They're available in sizes M to XL, although not in every color/size combination. (While additional color combination choices may appear on the product pages, the discount applies only to the colors black and white.)
