Nonsense. Literally the first random example I chose:

  Cheapest price: EUR 675
  Amazon price:   EUR 875

The vendors with the cheapest price have good customer reviews as well, unlike Amazon, which has terrible ones.

In Poland and neighboring countries, Amazon has some serious competition from Allegro.

In terms of usage, maybe, in terms of service, probably not. Often the biggest dogs are not the best. They have inertia and marketing, and that's why they're the big dogs. Not because they're providing the best, or the cheapest, good or service.

Depends on how local you go, there are local alternatives that are bigger in their domain for almost every domain in most parts of Europe. Amazon is much much smaller outside of USA and there are plenty of alternatives with better and cheaper service.

Also not true in Switzerland. Amazon was ranked #4 overall, #2 in tech, based on sales in 2024, with a massive distance to the leaders. It's not that popular around here, and with current U.S. boycotts I expect it to drop further this year.
