Where our money goes, how much we earn, our profits, our challenges and so on

The Amazon costs are nuts. The producers get peanuts and the middleman most of the profit.

I suspect Amazon's cost includes shipping costs.

In the US this would be $3.19 for EU fees see [0], and their referral fee would be $1.35

Distributor costs would include advertising, which is not cheap, as well as storage.

Aren't their mailing costs involved in buying directly from the website?

And those Amazon costs are much higher than I would have thought.
