Grocery business is almost a duopoly in Finland. Two national chains have about 80% market share between them. One of the chains has been running a delivery service for some time now, we've used it occasionally. You do the shopping list in the Internet, choose a delivery slot for the next day and pay when groceries are delivered. There's a fixed fee for delivery.
The other chain has a pickup service where they collect the items according to your list, but you pick up the bags from the store yourself. Again, there's a fixed collection fee. We haven't tried their service.
