Finally found some good deals from Amazon AU, not just price matching other AU Retailers but beating them.
Highlights are:
LEGO 42070 6x6 All Terrain Tow Truck $239.97
LEGO 41180 Ragana's Magic Shadow Castle $89.97
LEGO 31052 Vacation Getaways $71.97
Free delivery over $49. Bought the Technic Tow truck and finally used my $70 Amazon credit.
How do I get an Amazon $70 credit?
