Dollar Shave Club and Cosmo Kramer from Seinfeld are two fairly large trendsetters. One changed the way people bought razors and the other shaved with butter. Then Dollar Shave Club started selling shaving butter. Sure, it’s probably not the kind of butter you make cookies with, but if it offers the kind of shave Seinfeld promised, it’s worth a couple bucks. Especially now, since Dollar Shave Club is running a deal where your order includes a razor (first month ships free) and Dr. Carver’s Shave Butter (ships once for $8). After your free month trial ends, they’ll ship you monthly replacement cartridges for $9 per month. It’s a fantastic deal and since most, if not all, men do at least a bit of shaving, everyone’s going to gain something here.
