Originally built for cars, garages have evolved into storage units capable of protecting tools, sporting goods, and the identities of the world’s least famous rock stars. Pat your auto shack on the back with today's Groupon: for $40, you get a garage-door service call from Aaron Overhead Door (an $89 value). Groupon holders can also enjoy a 25% discount on any additional parts or services deemed necessary to return the door to full health.

Owned and run by the Conte family since 1968, Aaron Overhead Door trots out professionally trained technicians that know the ins and outs of any garage door. During the 30- to 60-minute service call, the garage whisperer performs a full checkup of the framework—tightening nuts and bolts while affirming that the door and its springs are balanced correctly, as regular use can gradually guide them off course. To ensure that the door sticks around long enough to store jetpacks powered by nail-polish remover, the tech also performs ample preventive maintenance such as lubricating, adjusting, and inspecting the garage door and opener.
