Optimus Maximus at Myer Parra Westfields. No price tag on them.
I don't recall anyone posting a sighting about MP Skywarp at TRU Penrith (or otherwise) at the time. *shrug*
Speaking of sightings, I found a single FoC Optimus Prime at Carlo Target yesterday; scanned for $28.
I don't have a checklist for that year to refer to, but as far as I know, Skywarp only ended up appearing at Toyworlds (which also got Starscream too).
Until someone can prove otherwiise, only Starscream and Ghost Starscream were at TRU (of the Jet MPs).
