I used to go to 1000000 Comix way back at their old location, where I would always pick up my comics and had a membership as well. They had a good location back then and it seemed a lot larger than where they are now on Yonge street. Their selection of comics is great, and it seems like they have shifted their stock towards comics and apparel, over toys and board games.
I have purchased a few things here and there, but I'm primarily a toy collector and their stock of action figures and collectibles is limited. They have the occasional GI Joe and Transformer, but they are a bit overpriced compared to their competitors over at 401 Games and Silver Snail.
I can't comment too much on the staff, as our conversations have been limited to "no we don't carry that" for the most part, but there are always a bunch of employees there to help you out. Overall a decent comic shop for the area, but I can't say I'm a regular due to their limited stock of collectibles and toys.
