But this is your opinion. I love the one he linked to and did not know about that they are so cheap at Costco.

What he and you prove as a point is that to him Costco deal is perfect while your "thick hair" it too thick to save money with Costco. So the Dollar Shave Club will be perfect for you (to save money) and useless to him. Therefore, the DSC will never scale well enough because people like me or OP will never have a thick hair :)
