Long time lurker, first time poster.
NOTE: I have scoured the JB Hifi website for this deal but can't find it - but I definitely got it in store yesterday (Osborne Park, WA). So the link in the post is generic.
JB currently have an (completely unadvertised?) deal where if you buy an S24+ at ticket price and sign up to the $59 month to month plan on a new sim (no porting) they give you a $500 discount. But you can just cancel the plan straight away and receive a net $441 discount.
$1,687 plus $59 first month less $500 = $1,246 total.
There is a slightly larger discount for the S24 Ultra and slightly smaller one for the S24. I don't believe it's on the iphones. The JB guys first tried to sell me on the 12m/24m plans (which have a larger discount) before revealing there was also a discount with the month to month. They described it as a silly deal because the new iphones are releasing.
It was weird how they did it - they sign you up for the plan and direct debit of first $59, then apply the discount via a physical $500 gift card they pull off the rack at checkout, and had to get a manager out to approve.
EDIT - this doesnt stack with the "bonus $200 gift card" they have on the website.
Why didn't you upload your receipt?
