I just discovered Apple gift cards were available through Entertainment. I can't see any time restrictions.
Definitely not as good as, say, when Coles / Woolies do a 20x rewards points (kinda sorta but not exactly like 10% off) when they happen, BUT when those aren't available, 3.75% is still better than 0%.
This is especially true after you've done any price-matching with the Apple Store peeps, e.g., I've had Apple price-match JB's 10% off Macs, and it'd be sweeter to pay with discounted gift cards on top, e.g., 13.75% > 10% off.
Details
Entertainment advertise it as "5% off iTunes eGift cards", but when you click through to redeem it references the "new Apple Gift Cart", with a "Debit card / credit card payment processing fee" of 1.25% of total order cost.
It also says "Buy up to $2500 Apple eGift Cards within 24 hours".
Available in denominations of $50, $100, $250.
Sorry but that's pretty bad..
Every couple of weeks 10-15% through Flybuys or Woolworths Rewards
