$40 Uber Taxi Credit for sign up and promo code

So Uber has another $20 credit since the last $10 credit in January. Just sign up and Uber gives you $20 credit, then click on the promotion tab, enter the code ABL1314 to get another $20 credit. Remember to change the taxi gratuity to 0% cause it usually sets to 20% of metered fare. This is kind of cool cause $40 credit is enough for 4 free short trips within the CBD or use you can use it for the taxi ride from the airport. Pretty cool for me. Make sure you act quickly cause the deal won't last long. Enjoy!
