Mitch Dowd is running an up to 70% off sale.
Socks are from $3.89
Jocks are from $5.89 (all sizes available on the ones I bought)
Shipping is $10, but if you sign up to their list you get a $10 coupon effectively giving you free shipping.
I used a throwaway email address and got the code about 15min after signing up.
Mitch Dowd are ok, and at 3 jocks for less than $20 seems decent to me.
