PostNL is the most reisje local carrier here. Ups is the best but almost never used, so far only by Apple. Dpd, GLs, etc, are all rubbish.
Maybe it depends on the location...
This is not just rural areas, either: even in major cities items can be delivered faster than the time it would take to find a store that carried the item, go to the store, get it, and come home again. It's really only suburban areas with a high density of big-box retail that even have the option to "go out and get something" immediately.
Amusingly, it's also only in these suburban areas where next day delivery even exists to compete. As an anecdote, living in the downtown of a major American city (population > 1million), the average Amazon delivery time is roughly 3 days, and last mile deliveries are all delegated to the USPS which adds significant time.
Every other store ships with DHL, which after several days pretends that they ring you, when they don’t, and then u can go pick it up at the DHL store a day later.
That’s their moat.
