the costco here has a 4 pack of merino wool socks for 10$. I bought one and the next week bought another. They are the same as smartwool socks as far as I can tell. Even if they are 1/4 as durable, they are the same price for wearing around. I have started wearing them pretty much all the time now. For hiking and such I'll still wear the newer design of smartwool socks that are made a bit better, but for everyday wear... you can't beat 2.50 for wools socks.
