>in real life, I mean, real estate is limited so why wouldn't darwinian market forces make a shop with product diversity + epsilon out compete a shop with a more niche spectrum of products

But can the employees advise me on which to buy?

I'll sometimes pay a premium to go to a specialty store, so I can speak to an expert.

(Ex: if I was going to buy a vaporizer, I'd probably go to a vape shop rather than spend days reading on the pros and cons of various models)
