“This holiday season Starbucks and Zipcar are teaming up to reward good Samaritans in Philadelphia. Zipcar will be driving around the City with life size magnetic versions of Starbucks signature red holiday cups attached to their roofs. When individuals stop to warn the drives about their coffee cup, drivers will then reward that person with a free Starbucks gift card.”

…still not going to get anyone to sign up for zipcar in Philly while PhillyCarShare is everywhere and cheaper.
