Brisbane: Maxtor 500gb USB 2.0 External Hard Drive for $99. New HT Store Opening Special!
One of their opening specials was the above hard drive, for $99! I believe it's the same as the one I've linked to (though less than half price).
Also said limit 1 per customer.
Just checked out the link then and under availability there is none at Indooroopilly, but maybe they'll get more in stock tomorrow.
If you're in the area, and need some cheap storage, this may be a good option!
(Though I personally prefer the WD myBook - www.wdmybook.com)
