After Macca's increased their price of a soft serve cone back up to 50c, Hungry Jack's (To the rejoice of OzBargainers) have lowered their price by 40% to a cool 30c.
With the exception of the Ikea bistro kids cone coming in at 25c, these could quite possibly be the cheapest cones around.
I'm not sure how much Hungry Jack's charge for Storm toppings, but this could potentially make a DIY Storm possible.
Sorry about the link, I could only find a Facebook post.
Oh… those cones…
