Just came across this - double the data on Coles prepaid for the next few months.
https://www.coles.com.au/our-range/our-products/coles-mobile
3GB + 3GB for $20 and 35 day expiry which is not bad for an in-store offer.
Vodafone have a better deal online only: $20 for 12.5GB and 35 days.
Change that to
"Coles Prepaid now 6GB for $20 and 365 Day Expiry"
and I'll upvote…
