Serendipity plays a role for me. My LHBS is 10 miles or so from my house and he remodeled his shop recently due to structural issues in his building, and also pivoted to becoming a cidery and winery, too, when he reopened the location. He also has an eclectic variety of beers on tap and packaged beer and wine.
He was an early supporter for Omega yeast (only 35 miles away), so he gets fresh Omega products regularly. I also have him order items for me on occasion. He also sells to his repeat and regular customers at a dramatic discount when yeasts are approaching an end date, knowing that we don’t mind making starters to proof a batch.
Not sure how much of that helps you, but I support my LHBS for all of the above reasons. If it were an hour away, I might feel differently, but I would probably time my purchases better and buy in larger bulk for some things, so that I could justify the travel.
