Via Groupon you can purchase discounted parking at Newark airport for about $4/day. This is extremely cheap, although typically this garage only charges about $8 including tax (so their website says). Newark Liberty Parking (http://www.parknewark.com/) is less than a mile from Newark Airport and offers over 1,500 self-park spaces. They offer 24-hour shuttle service, but no where on their site does it state how often shuttles run (which is important to me). I called the facility and was told they run every 5 to 10 minutes.

This Groupon deal expires 180 days after purchased and you can buy up to 4 per account. You can, however, only use one certificate per visit. There are four options to purchase:

• $4 for one day of airport parking (an $8 value)
• $12 for three days of airport parking (a $24 value)
• $20 for five days of airport parking (a $40 value)
• $55 for two weeks of airport parking (a $112 value)

I personally like flying out of Newark better than JFK for the sole fact of cheaper airport parking. JFK and LaGuardia charge an arm and a leg.

Enjoy your discounted parking!
