Was browsing Qantas Marketplace and saw they have a sale on for 30% off Amazon Digital Gift Cards when bought with points.
e.g. $50 gift card is 7,650 QFF points rather than 10,930
Doesn't stack with earn 4 points per $1 spent since you're paying with points.
Ends 11:59pm (AEST) Wednesday 17th September.
p.s. I know it's a better use of points to book flights, some people prefer just exchanging the points for cash value.
$50 GC for $76 worth of Qantas points even with the lowest 1c redemption.
