UPDATE: Chris (comments below) has advised he was able to get the deal in store as well as online. Call you local store to see whether they have stock.
Ok, I’ve triple checked the maths on this one and I can confirm this is a genuine 20% off deal 😛
Until the 9th of April (or while stocks last), you can get a $50 iTunes card for $40. Thankfully, you get free shipping as well.
You can get it from their online store here.
Thanks to Andrew, Karen, Chris and @dkjme for letting me know about this one.
