EDIT: Looks like it's been pulled from both cashback sites.
Important: Sign up to Digital subscription only as this gives the cashback.
To get the $1 for 28 day subscription, sign into either Cashrewards or Pricepal and click through to Herald Sun.
I have linked Cashrewards, as the cashback is $20.
With the varying levels of Pricepal cashback, it may be better going through them. They range from $17.50 to $31.50.
Going through either of the cashback sites will give you the $1 subscription offer, so cannot just link to Herald Sun site.
How do I wipe my arse with a digital edition?
