USPS shipping cost too high to Europe?PLEASE HELP if you live in USA?

[?]

Hello,
I have a question for people who lives in USA, expecially if you live at Denver, CO, United States.

I would like to order an item by Etzy shop, and the seller (from Denver) says that ship as: USPS First Class International

This have a tracking number? What I feel strange is the price... the item are just 100 seed beads (so you can image how light is the weight and the dimension of shipping in a normal flat tiny bubble envelope, so I don' t understand why the seller ask €1.80 EUR for the beads
and for shipping ask €9.73 EUR

Now, we know $ are inferior to € so

9,73 € in dollar the seller will receive something like around 18 $ !

I think to send a tiny flat envelope with some beads is too expensive!
What do you think?

What's the price for shipping from Usa items like this, with and without a tracking number?
Do you know both prices? (shipping TO FRANCE )

Thanks in advance for the info!
