Hardware stores contain the tools necessary to complete a home project, unlike software stores, which contain the programs necessary to make home projects feel pain. Experience the personal rewards of handiwork with today's Groupon: for $15, you get $30 worth of hardware and home goods at Jackson's Hardware in San Rafael.

Green-certified Jackson's Hardware, named Marin County's Best Hardware Store by Pacific Sun in 2011, buzzes with home-improvement experts who help visitors accessorize and maintain their domiciles with functional pieces and handyman tools. New showerheads ($3.95+) douse vertical bathers in smooth, aqueous streams, and door locks ($13.95+) and window screens ($9.95+) protect them from becoming horror-movie clichés. A new smoke detector senses the first waft of smog and alarms homeowners to ensure a quick evacuation ($7.99+). When finished flexing home-improvement prowess, follow the trail of sawdust crumbs leading to a trash can where construction carnage lays to rest ($22.99+). Invest in a hammer ($9.99+) to expand DIY capabilities, such as hanging up shelves or paint-by-number portraits of Charles Martel.
