Like what I stated on my OzBargain post, these code were actually sent to me back in late December but I only "discovered" it while cleaning up my email inbox this morning :P
Code: CheapiesUber
Discount: NZD $20
Expiry: 28 March 2018
Likely to be 1st ride only.
Referee: 50% off (up to $15) on five trips completed within 90 days.
Referrer: 50% off (up to $15) on their next Uber ride completed within 30 days of their referee/invitee completing their first trip.
Referrer gets $300-$500 once referee completes at least 30-40 deliveries.
Referees may be eligible for special offers based on the number of trips or deliveries they made after signing up through an invitation.
Can this be used if you've ridden in Australia before?
