Most sports grow out of a simple formula—ball plus stick, ball plus kick, or car plus explosion. Obtain the necessary integers with today’s Groupon: for $10, you get $20 worth of new and used sporting goods and equipment services at Kleen 'n Hard Sports.

Kleen 'n Hard Sports' experienced staff repairs and restrings threadbare sports equipment until it's worthy of entering the equipment emporium's Valhalla of new and used sporting goods. Every preowned pad, helmet, stick, ball, and color commentator springs back to life sanitized and deodorized after undergoing Kleen 'n Hard’s thorough cleaning system, which lays waste to harmful bacteria and steroid-enhanced microbes. Protect newborn hockey skates with a set of skate protectors ($6.99–$9.99) or prepare for handicap-hoisting golf courses by outfitting bags with a dozen used balls ($5.99). An assemblage of practice hockey jerseys ($13.95) can put the finishing touches on Wayne Gretzky–themed Valentine’s Day costumes. Kleen 'n Hard also sharpens hockey skates ($5), restrings baseball gloves ($10), and both makes custom golf clubs and unpretzels them after particularly frustrating bogeys.
