has Darn Tough Mens Steely Socks (2-Pack) (four socks total) on sale for $29.99 with free shipping. This makes it slightly better than the GoBros sale for this specific sock. It ships out February.
Yes these socks are expensive. You get what you pay for and they come with a lifetime warranty. See previous threads for more information.
*Note* I am wearing some Darn Tough socks right now.
*Update* The deal is now over. Congrats to everyone that got the pairs they wanted.
