Just logged in to my Uber app, and saw an ad for $10 off 3 rides codes, for use up to 27th August.
Could be targeted.
Just apply the promo code "MEL21AUG' in the 'Payment' section of the app and ride before Tuesday 27th August 2019.
Not sure if there's a minimum spend requirement as my App crashes everytime I tried to see 'More details' on the promo code. Also not sure if Offer is valid on UberTaxi or Uber Eats (Usually not). Code must be entered before you request your ride. Code is non-transferable and can only be used on rides in Australia. Does not apply to cancellation or wait time fees.
