Without manicures, fingernails would grow long and jagged, preventing businesspeople from using their smartphones and air travelers from packing their hands in carry-on luggage. Dodge this dystopian vision with today's Groupon: for $17, you get your choice of a spa mani-pedi (a $35 value) or a deluxe pedicure (a $30 value) at French Nails & Spa in Poway.

The experienced keratin whisperers at French Nails & Spa pamper paws amid neutral tones and periwinkle accents. During each 45-minute spa mani-pedi, technicians slather flippers with an aromatherapeutic spa serum before curtailing cuticles and exfoliating careworn feet. As hands relish a soothing hot-oil application, manicurists gently massage muscles weary from stress and egos weary from losing peekaboo contests to babies. Alternatively, the deluxe pedicure focuses on hooves with the same aromatherapy spa serum and a mineral exfoliating scrub. After technicians clip cuticles and massage dogs, guests select two additional foot-centric treatments, which can include a cooling gel, paraffin wax, callus treatment, or mask. Paraffin waxes and callus treatments soften epidermal sheathes, foot masks cleanse subankle pores, and cooling gels help toes impress their peers with esoteric music references.
