On Demand Car Service Uber has many different transportation options, but the cheapest is UberX which is a car-sharing service that can be cheaper than a taxi.
New users can receive $20 credit at sign up (with my referral link) and the credit does not expire.
After you sign up, head here to enter promo code C2E2 for another $40 credit, which expires 5/31/14. New users can combine the two credits for $60 in free credits! Nice! Only working for Chicago 🙁 Thanks, Catherine!
It looks like Uber specified it is only valid for Chicago. If you are looking to sign up for Uber, you can still combine promo code HIPMUNK for a free $25 credit (expires 5/2/14) OR promo code KALEB for a free $20 credit (expires 8/8/14) that can be entered after the $20 referral credit.
*Please note that my referral link is included in the post for the $20 free credit. Also, I couldn’t try the $40 promo code to make sure it worked because I am not a new user. If you have any problems or if it is no longer working, please let me know in the comments below. Thanks!
