Good question ! I have no answer for that! It makes me mad to see how much they charge and half of the cheaper disposable razors are junk. They give you a great price to buy their razors and then charge the heck out of you for replacements. It's a total rip-off ! I was thinking of joining Harry's Razors as they have monthly replacements for a whole lot cheaper !
They're just like the companies that make printers. They sell the printers real cheap and rape you on the ink cartridges.
Dollar Shave Club is still a rip off. You can get a year's supply for a lot cheaper at www.dorcousa.com/ where Dollar Shave gets their razors from.
Name recognition ... Pure and simple
