Disposable razor blades are expensive. Insanely expensive. $3 per cartridge expensive.

Fortunately, I only have to shave twice a week. Still, it annoyed me when I had to go to Costco and lay down over $40 for blades.

I found this video, tried it and have been using the same cartridge for a few months now. Yes, it really works.

Anyone else have any tips?
