COTD has a toy sale on today (as advertised in The Age newspaper). You can find it at www.cotd.com.au/wtf and among the Transformers on offer are:

Human alliance basics @$8.99 each - some from the later waves that I don't think we saw here in Australia
TF Prime voyagers @$29.99
DOTM Cyberverse 3-in-1 play sets @$18.99
DOTM Ultimate OP @$99.99

Not sure how the site works, but suspect you may need to register in order to make a purchase.
