Amazon sells a slightly different but much wider range of "cheap plastic crap" thanks to FBA. There's no shortage of budding sellers with an Alibaba account who think they have the next best thing (read: re-labeled, generic Chinese crap) and flood the market with crazy cheap products making it difficult for bricks and mortar retailers to compete.

A store like Toys 'R' Us may have a slight advantage when it comes to licensed merchandise, but I think even most of the big sellers long ago accepted that it's impossible to ignore the Amazon juggernaut and now also sell on the platform.

I'm not an expert, but based on casual observation, yes they do.
