Personal grooming, like apprehending a serial toilet-paper thief, is a service to the whole community. Make a gift to yourself and others with today's Groupon: for $9, you get a one-year supply of Ninja razorblades, plus a waived membership fee to the Dollar Shave Club (an $18 value).

Dollar Shave Club delivers high-quality shaving implements directly to the doors of both men and women. Members receive 60 cartridges in one shipment, enough to maintain a satin-smooth face, body, or cat until the next delivery. The Dollar Shave Club's signature Ninja blade close-crops hair with two stainless-steel blades and a pivoting head, allowing the razor to glide smoothly over epidermal terrain. A conditioning strip of aloe vera lubricates skin, sparing shavers the inconvenience of postshave petroleum baths. While each member receives a complimentary shaving handle, the Ninja blade will fit neatly into any Sensor-compatible handle.
