100 years ago people regularly ordered things for delivery. Sure it wasn't online, but all online gives you is some time.
E.g. "milkman" is a word in English. Today, most people haul their own milk home from the supermarket.
Certainly, as you go back in time, there was a lot of local delivery especially in urban areas. Mail order, Sears catalog notwithstanding, less so. Just to pick one random example, ordering music, movies, or books pre-Amazon was really pretty limited.

And a lot more types of goods available. Again, 25 years ago, it would not have been practical for people to have wholesale pivoted a huge amount of shopping online. (And companies like B&H Photo couldn't have scaled.)
20 years is probably just about the cusp of it barely being possible.
