This is valid in-store only today, no online coupon, so call into your local Coles. This works out to be $99 for the $150 SIM, or 34% off.
For note, the $150 SIM page on the Coles Mobile website lists it as $119 (with an tentative expiry date of yesterday, 27 Sep 2022), so this pricing might be available in store. Can't see a Coles Mobile deal in the catalogue but worth a shot asking in-store.
Powered by Optus and supposedly Coles Mobile wasn't affected by the recent hack.
