Technically not a deal but a big money saver.
Accidentally found this free NSW government published app which shows the fuel prices in real time, highlighting the cheapest one on the map. I saved 10 bucks today just by driving 1km from my usual woolies servo which I thought is saving me money with their 4c discounts.
I feel ashamed as an Ozbargainer for not knowing about this before so decided to share it here even though I might be breaching a few deal posting rules :)
