Like penguins, golf balls mate for life, but unlike penguins, they tend to drift in deep water. Ensure multiple loyalties with today’s Groupon: for $5, you get a large basket of balls at The Practice Tee Driving Range (a $10 value).

Friends of the fairway score skills in Practice Tee’s swing-perfecting facilities. Master the short game and show two target flags who’s boss in the 30-yard chipping area. The putting green’s synthetic turf encourages putting subtlety with the smooth surface of a flexible emerald. With no age restriction at the driving range, multiple generations and an unlimited number of players can benefit from this deal’s fresh basket of sky-targeting spheres. Though not included with today’s Groupon, the facility's mini-putt course keeps small hands, small bets, and small architecture busy, and after balls and brains are exhausted, the driving range purveys discs fit for either a rollicking game of disc golf or a do-it-yourself birdbath.
