Ask HN: Amazon Becoming a Monopoly?

Hey folks,

I've seen that Amazo has implemented a while ago "international shipping" → basically if you're from EU(as example), you can order from amazon.de and get it in a country that doesn't have amazon(as example: Romania). I've ordered something and got my stuff in 1 week(Germany to Romania).

And I was thinking: Is it possible that Amazon could become a monopoly in the market? Since they have sellers from all around the world and looots of products: they basically inhibit the local marketplaces with products. And yeah: they are the biggest marketplace in the world.

How would local marketplaces react to that? Would Amazon be the main marketplace all around the world?

Cheers!
