As one of its daily deals, 13Deals offers the FILA Men's or Women's Performance No Show Socks 12-Pack for $12.99 with free shipping. That's $1.08 per pair and tied with our mention from two weeks ago as the lowest total price we could find by $7. (We saw a similar 12-pack for a buck less in July.) They're available in men's sizes 10-13 (shoe size 6 to 12.5) or women's sizes 9-11 (shoe size 4 to 10). Color is chosen at random. Deal ends September 18.
