How to Avoid Being Ripped Off:
Replace the blades less often. First, those guidelines that say we should replace our blades three or four times a month come from the companies that are selling the blades. Now, these guys do know razors, but because they also know "taking your money," they might not be the most trustworthy source of advice. Instead, try replacing your blades when they stop working. And you can keep your blades working a lot longer with a few easy tips, also conspicuously absent from the razor blade cartel's promotional reading.
Razor blades don't dull from cutting your soft doughy face, nor even your food-encrusted whiskers -- the dulling effect actually comes from water and air corroding the metal. You can greatly limit that corrosion by simply drying the blades after each use -- blotting them on a towel is the easiest technique, but other people have had success with dipping them in alcohol, blowing on them really hard or throwing them in the direction of the sun.

How to REALLY Avoid Being Ripped Off:
Pluck your face. Tweezers last basically forever, so it's economical, so long as your time isn't very expensive, which, let's be honest here, Cracked reader, it probably isn't. Also, the confidence you gain from plucking every hair on your neck and face will give you a demeanor that many observers would describe as "wild, s**t-eating intensity" -- which will certainly come in handy during business negotiations or when staring down any hostage takers.
