Thanks to their 24/7 customer service and 365-day fast and free shipping, Zappos.com makes lots of people happy. So with that in mind, we decided to take happiness to new heights by committing random acts of happiness across the US. We randomly delivered fast and free pizzas to people in Boston, MA. We filled eggs full of free Zappos products, hid them throughout Portland, OR and tweeted clues to their locations. And we gave people free rides in fast and free shipping taxis in San Francisco, CA. The result: three random acts of happiness and thousands of happy people.
