Hello Ed,
Thank you for your message, I know that sending goods to the USA is no more easy, but here is how it works:

- All prices are given ex-VAT, in many countries outside the EU, we do not have to charge the VAT

- On these prices 10% tariffs have to be added and paid by you, money is collected by the French Post and send to the US fiscal administration.

- Shipping charges are by weight:
€ 17.30 for parcels up to 250g, € 19.30 for parcels up to 500g, € 29.10 for parcels up to 1kg, € 43.00 for parcels up to 2kg.

As I told you, things are no more easy
Meow!!
