Does anyone use this service? I'm on this kick about how much razors cost me a month and I just found out about this site today. I have been using the single blade disposable razors for years and they're so expensive. Last week I purchased a Mach3 with 15 blades, but it was pretty expensive. I did find a video on youtube where a guy said to run your razor up and down a pair of jeans 20 times and it will sharpen the blade. He stated that you should get months out of one blade using that trick. People posted in the comments stating that it really works so I want to try it. But this site DollarShaveClub sounds like a no brainer. Get 4 razors a month for 6 bucks. I might even throw in a One Wipe Charlie while I'm at it Does anyone use this service?
