On the road, running low on petrol, and want to take advantage of those Everyday Rewards discounts you've stored up? The Woolworths Petrol site lets you find the nearest Caltex/Woolworths branch.
The search is pretty much what you'd expect: enter an address or postcode and the nearest options show up on a map. Woolworths claims the site is mobile-friendly, offering a small-screen friendly rendering on portable devices. With that said, it failed to work properly on my BlackBerry, which isn't exactly an uncommon choice. If you're looking for the cheapest fuel rather than a particular brand, check out Google's Petrol Price Tracker.
