Picked up this Wifi Modem @ Austpost to go with the $70/month Optus 100GB plan. It scans at $39, but it shows $29.50 at the display cabinet. Check to ensure the display cabinet shows $29.50 before buying. The staff will need to override this.
I am assuming this is Nationwide as I saw this at 2 Austpost shops in Melbourne CBD.
If you're in Sydney, $22 from Wireless 1 and it's unlocked…
