EB Games has a (delightfully non-specific) deal at the moment on iTunes gift cards.
Got the email this afternoon saying they have 2 for $30, so 25% off.
Pretty good and standard reduction, but if you need to stock up for any reason it might be handy.
It also doesn't mention when the deal ends beyond "For a limited time only!". Awesome. Hope this can help someone!
harvey norman has the best deal ive ever seen. every 6 months approx buy one get one free. so i usually go to my nearest 5 harvey normans to stock up 10 :). Still a good deal OP, will get 2 tomorrow :)
