People who purchase movie toys at ToysRUs in Taiwan during April 28th to 30th, have a chance to win some limited edition movie redeco toys.

Purchasing over NT$6,999 gets entry into a battle damaged Deluxe Bumblebee (looks like hand-painted, to look like a worn toy).
Purchasing over NT$9,999 gets entry into a battle damaged Voyager Optimus Prime (also looks like a hand-painted worn toy).
And it looks like all entries are eligible to win a metallic/silver coated Optimus Voice Changer helmet.

No amount of each is noted, but is likely to be very limited... probably less than ten of each.
