I’ve been doing a bit of back-of-the-envelope math, and discovered something rather shocking. If a four pack of carts lasts for two months (and that is being generous, in my experience), I’ve spent less on shaving gear since I started traditional wetshaving than I would have spent buying carts… and that is despite me having eighteen razors, ten brushes, twenty-six or so soaps and cream, and a few years worth of blades.
