Since I'm on the lookout for good razor/shave deals, I thought I'd give ShaveMob a try. This is a link they provided us to share with our readers ShaveMob. I paid $21.99 for 12 cartidges, and the razor handle. This is cheaper than I get at the store. I got the six-blade package. The package is designed for six months, but I actually change my blade weekly since I worry about bacteria developing.
