just got a call from Microsoft staff offering me a 30% of my renewal with the following voucher code:
AUONLY30.
It should work for new and renewal subscriptions at both Standard and Professional levels.
New subscriptions:
$236 - discounted from $337 - TechNet Standard
$433 - discounted from $618 - TechNet Professional
Renewal subsciptions:
$182 - discounted from $260 - TechNet Standard
$306 - discounted from $437 - TechNet Professional
Comparison of versions can be found here: https://technet.microsoft.com/en-au/subscriptions/buy/hh4429…
This code has been going around for quite a while. I think it's still cheaper to buy off Amazon anyway?
