Spotted this the other day in the mail, Tandy have 25% off Remote Controlled toys, which does actually include the three Movie RC toys (Barricade, Optimus, Bumblebee). Myer had these for $20 each, but the one I found yesterday cost me $9.74, from their regular price of $13.
I can't remember when the sale ends (can't find the catalogue), but I think it was for a couple of weeks after Christmas.
