I didn't know that. Any examples?
Two that I can think of off the top of my head:
Target Bumblebee Two Pack
K*B Toys Action Fleet Remote Control AT-AT (This is about 8 years ago).
I KNOW they've had a few other things that were Target exclusive before - I think Hot Wheels, Superheroes.... and I think another Star Wars thing.
But I either wasn't into them, or didn't care enough to remember. ;-)
The AT AT I actually bought at Zellers. And I saw the bumblebee one with my own eyes ($35.00 - yikes! - It was $16.00 in the U.S.)
