The Autumn sale has started, with 101 Transformers products on sale (as of this posting).
There are quite a few recent items on there, but the item worth noting is "Titans Return" Trypticon, at 55% off, which is about AU$160 before shipping and GST... which I would think would end up being a fair bit cheaper than the ones still available here at Toyworld or Myer at $300.
The Japanese version is almost identical to the Hasbro version, but for some reason has different coloured screws. It also has a different box and paperwork.
