I had been intending on buying black socks anyway but the ones I had looked at elsewhere were the thin ones that slide down so I declined. The salesman offered me half price socks as I had bought shoes so I bought the 3 pack. They are a nice medium thickness, the kind I really wanted. They are also a perfect comfortable fit and excellent price.
I felt that by the time I had left the shop I had made really good purchases.
I will certainly be back and will recommend Mountain Warehouse to friends.
