Nails, if left to their own devices, would spend most their days scratching off lottery tickets and activating scratch-and-sniff greeting-card scents. Keep nails on your side with today's Groupon: for $17, you get a signature posh manicure (a $13 value) and signature posh pedicure (a $22 value) at Posh Nails BK in Prospect Heights (a $35 total value).

Posh Nails BK's nail detailers revitalize and pamper men's and women's fingers and toes using high-quality products, such as Essie, OPI, CND Shellac, and Seche Vite, and double-sanitized or disposable tools. After a dip in the jet-free pedicure sink, which is cleaned after each client spends time frolicking in its water, cuticles are trimmed, and toenails are buffed, shaped, and painted to a dazzling sparkle. While complementing a brand new set of toes with factory-fresh fingers finished off with a selection from a rainbow of vibrantly colored polishes, clients can gaze at TVs or absorb the tingling rays of WiFi. Customers can also apply the value of this Groupon toward a manicure or pedicure upgrade, including a paraffin manicure ($20), tantalizing citrus spa manicure ($25), and the cool mint spa pedicure ($40).
