Been using DSC for a couple years now. I get the high end blades that I think are $9 a month. I am only a 2-3 shaves a week guy, so I have the blades delivered every other month. Even at that rate I still have extras. I think their customer service is really good too. I like that you can push off the delivery of the blades for an extra month if you still have a good supply on hand. I think the quality is decent enough that it makes it very hard to justify the $30 store bought blades ever again.
