I looked up the Dollar club the other day. Several guys I work with are members and like it. I was curious if they offered DE blades, they don't. But then again, it is cheaper for me to purchase my own in bulk. It is a great business model and I have not heard any negatives.
I did some research on the Dollar Club and found out that they're just reselling DorcoUSA handles/blades on a subscription basis. It may be cheaper to buy the blades in bulk from DorcoUSA than a few a month from Dollar Shave Club.
