KIWICOMMUTE15
Uber, the taxi/transportation app, is offering $10 off a ride for a maximum of 2 rides for June 5 only.
Sourced the deal from Mauricio Freitas, Geekzone Owner. It is also mentioned on Dannews' Twitter.
Note this is a promotional code and NOT a referral code. I tested on my existing account and it works but note that it only applies to rides in New Zealand.
If you are a new user, use a referral code from our wiki and you will get $25 credit.
Then once you are set up, use KIWICOMMUTE15 in the promotions box within the app and you will get a message that says you will get $10 off on 2 rides.
