Amazon has no direct presence in Switzerland, but you can order a fraction of its products from neighboring countries. Many products are not available, mainly because nobody wants to deal with customs once the product crosses the EU boarder.

Amazon itself never moved into Switzerland in the first place for many reasons (small market, unusual customs situation, relatively high salary for warehouse workers), and in the meantime the largest Swiss supermarket chain created an Amazon clone which became hugely popular pretty much immediately: Galaxus.ch

There are alternatives throughout Europe. The Balkans have Emag, Benelux has bol.com. I think in both regions Amazon is less popular. I'm sure there are other examples.

The Netherlands has plenty of them. Tweakers.net is a price tracker for electronics and such (eg: computer parts, phones, laptops etc) and usually it's easier to find a shop cheaper than Amazon. I have some go to stores for my needs because their content is organised way better than Amazon. I also find some alternatives better than Amazon because they have free next day shipping, something that's not free on Amazon.

Emag in Romania. I hate it, they bought most of the competition, they did a lot of anticompetitive things, but it's really easy to buy from them.
