This is the same product sold at different prices. In one case, Dr. Leonards catalog sells the “Barber Magic” hair trimmer for humans is $12.99. But if you want to use it on a dog, it’s only $7.99. Freakonomics tells us this is an example of “price discrimination.” I’m just glad there’s now a less expensive option for getting out my burs, mats, and tangles.
