D'oh,
In all my rambling, I forgot Penney's and Sears as well. Both had toy Departments, though as I recall, Sears only had one at X-Mas and their catalogue. Doesn't seem like many remember shopping at Penneys for Toys though.
JCP, where I actually did my management externship, had a kick ass toy aisle in the one corner, and they had weird toys you couldn't find elsewhere either. Sorta expensive though as I recall, but they were the ONLY place I saw Micro Collection. Got my Bespin and Hoth sets there. They also had the Dungeons and Dragons figures (poseable and the pre-posed pre-painted things) as I recall.
Very little otherwise though... Catalogue had more.
Sears Catalogue had all the weird junk that I was told was a waste of money... Sears Cantina, the Cobra base, etc... In reality, they sort of were because cardboard didn't handle play well, but my older brother did get a Cantina because I recall the blue Snaggletooth.
I remember getting MASH figures at Sears Stores (another odd, uncommon toy) that I used as the doctors and civilians that Cobra would kidnap and G.I. Joe would have to save.

I had Winchester, Hot Lips, and Hawkeye.
I wanted the trucks, but every jeep or ambulance was broken in its box. The playset looked cool too.
Did anyone here collect STARCOM: The U.S. Space Force? This was a mid-80's toy, but not one I see many people into. I have a pretty complete U.S. collection, but none of the foreign vehicles. I loved STARCOM though. There's a single site dedicated to them.
