Swan Taxi in WA are giving 20% off for those using the swan taxi app. I found the app easily in App Store.
When signing up for the app you’ll need to verify your mobile number and the deal will come up straight away as a pop up.
Discount runs until 2nd Jan. there is some fine print - the main one is minimum $10 fare.
It should work out cheaper than Uber in non peak swan taxi times (eg weekday daytimes). It’s probably cheaper than Uber on weekends and nights. Swan cabs have a $2 airport surcharge in WA and similar surcharge after midnight on Friday and sat night so factor all that in when comparing to Other companies pricing eg Uber govt surcharge and their occasional peak pricing surcharges.
I have been using Shofer. New, clean cars, cheaper than a Swan taxi (at normal prices). Not trying to turn this into a flame war, but I will not readily forget the trip in the taxi with the lit up "check engine" light, or the one where the driver did not match the photo of the ID. I did also have some good taxi drivers, but it's been a mixed bag.
