What makes them different than this place? I've never been to the store in the article. Maybe its because they're still trying to sell new books, and the thriving stores are all selling used books?
So many people I know (anecdotal, for sure) seem to still prefer to read physical books. Even younger people, in their early 20s. Beyond that, some people will still want to collect the physical representation of something they really love.
Certainly, this will not be as many people as before ebooks were around. Still, there has to be more to the story with this one store. It doesn't seem to add up.
