Not really.
I've been cutting my fiance's hair for 3 years. He likes to keep it trimmed perfectly, so he needs a trim every 3 weeks. Figure $15 for a cheap cut, and that's $780 over 3 years. We paid $22 for this kit, so that's over $750 we saved. We're brokeassed, so that's a nice bit of money. We could take a 3-day/2-night trip to Florida on haircut savings.
