If the game Monopoly taught us anything, it's that owning a car is a responsibility equal to that of owning a dog (or a thimble) and that free parking is something that happens to other people. Be less responsible with today's Groupon: for $11, you get three days of covered parking (up to a $33 value) at Blue Sky Airport Parking.

Located a short jaunt from Sky Harbor International Airport, Blue Sky Airport Parking equips Phoenix fliers with traveling convenience and the reassurance of a secure car. Arrive at the lot on the south side of the airport and relinquish your ride to an accommodating parking spot inside the fence-barricaded, video-monitored parking lot, ensuring your car will be guarded from potential thieves or 19th-century impressionists looking for something more experimental to paint on. After providing parkers ample time to exchange teary-eyed goodbyes with their sedans, an airport shuttle arrives car-side to load luggage and whisk travelers to the airport. Upon landing back in the heart of Arizona, Blue Sky's airport shuttle will swiftly transport automobile owners back to their eagerly waiting vehicles for a cheerful reunion.

Though Blue Sky Airport Parking sometimes features a discounted price online, this Groupon still offers the best deal available.
