Because you're too busy to choose among 20
brands of white socks. Time is money!
Price/Quality: the sweet spot
We strive to pick the reasonable tradeoff between quality and price. Don't compromise on quality, but don't overpay.
Buy the stuff over the Internet and get it delivered. You shouldn't have to leave home to get a pair of socks.
There will still be plenty space left for your personal touch, if you are into that sort of thing.
