I went to my (not-so) local TRU today, a 1/2 hour drive away, having to pick up an unrelated courier parcel. I bought the Swamp speeder, as well as the Fire Blaster, and went to check-out.
They were out of Chrome Stormtroopers!
One of the ladies explained that they didn't receive very many, and that they were all out. She gave me a Lego Santa key chain instead, of which they still had many. They mentioned that they might be receiving more.
Considering the store had opened at 9:00 am, and this occurred around 10:10 am, they either had a hoarder grab them all as soon as they opened, or the store started to give them out before it was supposed to.
The staff were very helpful, especially the girl at the cash, and there was a lineup forming behind me, so I didn't ask them for any further details. It was a little disappointing, however.
Oh well, I can always order one from S&H.
