Big W's online store is a frequent source of discount iTunes gift which we've often highlighted on Lifehacker. However, there's one apparent downside to the bargains: the online division appears to be pretty inefficient when it comes to actually activating the cards so you can use them.
Several Lifehacker readers have commented on our most recent Big W post that when their cards were received, they hadn't actually been activated. If individual cards aren't activated, then they can't be redeemed (a precaution which means there's no value in a shoplifted iTunes card).
Blogger and tech journalist Alex Kidman (who, yes, is my brother) had the same problem. He eventually got it resolved, but only after repeated contact with Big W. The moral of the story? Big W online doesn't seem to do a particularly good job of selling usable iTunes cards, so bear that in mind the next time they have a special. And whoever you buy cards from, make sure they're activated in-store before you leave.
