Was at Coles last night when they had announced on their PA that they had 20% off iTunes cards. Checked catalogue, and there it was (see pic).
This wasn't listed under the catalogue specials for the week.
Pretty standard iTunes discount - at least you don't have to buy more than one, and as always you can price match at Officeworks.
DSE has $40 for $50 card delivered atm:
