Thought I'd make a deal about my findings here
$31.43 brings a month of time down to $15.70~ a month - even less than the $16.50 it was last year directly through Battle.net for a single month sub.
Currently the cheapest WoW time is $17.25/m if you buy 6 months of time ($103.50)
3 Months of time comes to $18.60/m ($55.80)
and a month to month sub is $19.95/m
These cards will activate as long as you have a US WoW account, so you can ignore the "Can't be activated in Australia" message.
I don't think these time cards have an expiry date, so you could hypothetically stock up now and activate them prior to WotLK/Dragonflight expansions.
Looks like Dragonflight is also cheaper than the Bnet store at AU $51.27
I don't play world of warcraft.
