A simple question to ask is: As opposed to selling online and having the world as your audience, are there enough card collectors in your area to support a card business?

I live in a big neighborhood in a big city. I'm sure there are not enough sports card collectors to support a business. Other-sports? I don't know.

At the least, I would sell online to see how that works. If you're really good at that, then do your homework and think a brick & mortar shop is viable in addition, maybe.

But there's a reason that card shops have gone out of business all over. Will with new card prices on the rise, will things change? (shrugs shoulders)

That someone had romantic dreams and really wants to do it, doesn't make a good business plan.
