Wouldn't you be competing with Amazon.com, which can deliver <i>any</i> kind of socks to your door (with free two-day shipping for Prime members)? Not to mention that Amazon can send you underwear (or anything else you want) with the same shipment.<p>I can't see myself maintaining an online account with a separate business just to get one type of item that's easy to get elsewhere. I'm much happier just dealing with Amazon for all my needs (and yes, I do buy socks there).
This may be pedantic, but there's a couple typos on <a href="https://bulkblacksocks.com/socks.html" rel="nofollow">https://bulkblacksocks.com/socks.html</a> which make me think twice about signing up.<p>'Heals' is a pretty critical one. Even though the service is dead-simple I want to trust my socks source knows the distinction.
Not sure about the rest of the world but all* Australian supermarkets have a socks and undies section where you can pick up a 3 pack of black (or white) socks for about $9AUD.<p>*All in this case being the two major companies.
