Coles Airport west have wave 3 Beast Hunters Legions for $7 each (Blight, Rippersnapper, Windrazor) I grabbed 1 of each but there is still 1 left of each plus 2 prowls and a soundwave (and wave 1 legions)
Now all I am missing is Hun-Grrr

Also Big W in Sunbury should be about to put out some construct-bots since I saw some boxes labelled TRA Construct Bots Scout class and elite class while I was there that hadn't been opened and put on the shelves yet
