The Shelf Audit Files No. 03 — The Grooming Aisle

Two clippers sit on the same shelf. One costs $40. One costs $120. Everything about that display says the $40 one is the deal, and it is not. Once the reason is clear, it cannot be unseen.

The reason is one question the box never answers on the front: can you buy a replacement blade for it, sold by itself? When the $40 clipper goes dull, and it will, there is no blade made for it. The whole thing goes in the bin and another one gets bought. When the $120 one goes dull, a new blade snaps on for about $26 and it runs another decade.

This book gives you all ten brands from the video: the five running the trick, the exact trick each one runs, and the five that a household can keep on a shelf for ten or fifteen years. Every price, every blade part number, and who owns each company. It is about hardware and money — what a tool costs and what you can replace on it — never about what any of it does to skin or hair.
