This one slipped under the radar while the other big mid-year toy sales were going on at the moment... and this could well be Target's mid-year toy sale, as it includes their price-match guarantee, which is usually only valid during the mid-year toy sales of them and other stores. (and haven't seen any advertising yet for their usual "Australia's Biggest Toy Sale" which they usually do by now to encourage shoppers to not spend their toy money at BigW's sale)

The catalogue can be found here. The Transformers items are on page 11.

Scan of the catalogue page, and the price-match policy for 2017 (if any of the store give you problems matching any Australian-owned Australian *online* store price).
It's on page two of the catalogue, but also here as a pdf on their website.
