If you haven't tried Uber, the time-saving service that lets you hail a cab, reserve a black car or book a ride share via their fantastic app, you should, if only because this deal, the best we've ever seen, is so good. Get $45 in free Uber credit via the following two-step process: 1) setup a new account here using the $20 off on the page; 2) login to your new account and then add another $25 off credit here by entering code Hipmunk. The $25 off credit is only valid on your first ride, so make it a long one. It also expires 5/1. The $20 off works on multiple rides and does not expire. This is hard to beat and may end very shortly.
