Keeping clothes clean requires constant vigilance against top-heavy ice-cream cones, deceptively deep rain puddles, and militant cotton rights activists. Cleanse smudged up duds with today's Groupon: for $7, you get $15 worth of drop-off laundry services at Holland Laundry. For drop-off services, a 10-pound minimum of washables is required.

The friendly staffers at Holland Laundry suds threads of clothes and linens, fluff them dry, and fold them with precise, practiced hands. Sullied garments spiff up with a fresh-smelling lather ($0.95/pound), and other washables such as comforters, rugs, and reputations ($1.25/pound) return to owners crisply folded and refreshed. The convenient drop-off service, plus free bleach and softener available for all drop-offs, frees customers' schedules and takes a chore off their hands, leaving them with more time to relax and ponder the twist ending of Mary Poppins.
