Price in Euro or Dollar...

IN EUROPEAN WAREHOUSE:
1. When ordering I looked at the products and found everything priced in Euro = OK.
2. When I payed by Paypal, everything went into Dollar = WHY ?
3. And when I controlled my account and bill this was in Dollar too = CONFUSING !
The possibility for own price control is awkward.
In my mails I can't even se the Euro price on my order either - this could be more smart :-)
