Update: New users can now receive a free $10 credit when you sign up.
I previously tried and wrote about car-sharing service Lyft last month, but there is a new promo code available now to help celebrate all the Fourth of July Festivities in Boston! Use promo code BOS4TH to snag a free $20 credit when you sign up for a new account. As mentioned in my previous post, a $20 credit can get you pretty far around the city, so if you do not use all $20 up on your first ride, you can use it again for your next! Pretty sweet!
Have you had a chance to try Lyft yet; what did you think? Have you seen pink mustaches on cars around the city too?
And check out the blog later today for events and ideas around the 4th of July in Boston to use your free ride to!
