Car rentals are like friends—though it's acceptable to take them grocery shopping, it's unacceptable to spill soda on them before abandoning them on the street. Treat a rental car like a true friend with today's Groupon: for $35, you get a one-year membership with a waived application fee (a $25 value) plus $75 worth of driving credits to apply toward car rentals from Mint (a $100 total value).
Mint hands automobile-less clients the smartcards to unlock fuel-efficient vehicles in hopes of reducing traffic, pollution, and humans' dependency on fossil fuels. After registering online, customers can nab cars at one of Mint's many pickup locations and use their 24-hour rental credit over the span of multiple errand-running sessions, wheeling about town with prepaid gas cards. Once their car-borrowing days are over, drivers adhere to the autos' and parking spots' prenuptial agreements by returning the rentals to the exact spot where they found them. Mint's FAQ page provides answers to a slew of questions to help motorists wrap their brains around the car-rental process.
