EXTRA20
As WatchNerd says, everyone needs an el-cheapo quartz watch in their collection for those times when you just want to grab 'n go. I don't know what their quality is like these days but I always remember Timex as making dependable, if not over-exciting, time pieces at a good price. Discount also applies to accessories on sale, too.
Ensure you select AU$ when you reach the site to avoid currency conversion charges, plus you can use PayPal at the checkout. I've tested by adding a few items to the cart and it's never gone about AU$20 for express shipping, but it's free for orders over AU$190.
