Many physical bookstores have web pages where they sell e-books as well. Find the store that serves what you want, instead of finding faults with the ones who don't and going with the huge sell-everything-store.
Or I can go with the huge sell-everything store because I'm perfectly fine with the service it provides. Not everyone is looking for some bespoke curated experience when buying a product.
In short, the store that serves what I want is usually the huge sell-everything store.
