Supermarket delivery in the UK has been fantastic, much better than Finland. I think you are right about the population density, and also the amount of competition between 8 large supermarket chains in the UK, vs the near cartel like situation in Finland.

Another example would be automated checkouts - that came much later in Finland compared to the UK. I think there's a good point there that the duopoly stifles innovation, plus there's just a much smaller market and less pressure to scale up.
