From a Qantas email:
Never miss out on earning Qantas Points again!
Discover the Qantas Shopping Points Prompter – a free tool for your browser that alerts you of points-earning opportunities when shopping online. Install and shop via the Points-Prompter and you’ll earn 500 Bonus Qantas Points on your first purchase over $100 before 30 June 2020. Even better, that’s on top of the points you would normally earn.
For more information on the Points Prompter, I wrote a post on it last year, also included in our post : Free / easy ways to earn Qantas Points.
