10% off external hard drives @ Harris Tech (1TB for $314)
I ordered a 1TB Western Digital My Book Essential for $314 plus $6.52 delivery. The 750GB Western Digital My Book Essential was slightly better value at $224, but I opted for the larger drive. The Western Digital My Book Essential drives come with 3 year warranty according to the HT website.
The cheapest I can find on Staticice.com.au is $350 for the WD 1TB and $278 for the WD 750GB model.
