Though pearl prospecting is a lucrative labor, scooping sand is tough on delicate toe-diggers. Today's Groupon soothes scraggy digits: for $17, you get your choice of a chocolate or peppermint pedicure at Koi Nail Spa in Sanford (a $35 value)

The licensed nail techs at Koi Nail Spa work hard to pamper clients in a thoroughly sanitary and stress-free environment. Begin a 30-minute pedicure with the embrace of a gloriously pleasant hot towel and a sweetly soothing chocolate or peppermint mud-mask application. An exfoliating foot scrub repairs dried-out leg endings and prepares them for an extensive double-length massage, which softens soles from heel to toe. After the finishing touches have been applied, patrons leave Koi energized and invigorated, ready to run a marathon, complete a walk-a-thon, or watch a telethon without falling asleep face-first in a bowl of popcorn.
