The Good Guys website is hands down the worst organised website of a reputable store ever.
Pricing varies for the EXACT same item by so much. So it was no surprise to find some bargains in there amongst some absolute atrocities.
If you're in the market for an iPad/iPad mini, have a look. I found this mini with Retina which is $21 off apple prices and cheaper than Kogan too. There were a few other models that were cheaper, and with $0 charge if you pick up from in-store.
EDIT: Save an extra 2c from Big W for the 64GB Model - http://www.bigw.com.au/electronics/computers-office/tablets/…
