Okay Sandi - I don't speak italian but spanish can get you pretty far and the fact that I buy everything online.
Go to this site
Click on the shopping cart icon.
Click on invia l'ordine
(with the arrow to the right)
Click on Sei un nuovo utente? Registrati
You'll need to register before you can order. Here are some field translations:
*Cognome - Last Name
*Indirizzo - Address (like 1234 Main Street)
*Numero civico - put in the letters snc
*Indirizzo - I think this is like apartment number
*Localita - City (San Diego)
*Provincia - State
*Codice Avviamento Postale - Zip Code
*****one - Country (from a drop down list)
*Partita IVA - put none
Ok, now mark the circle next to the credit card pictures and check the box that says Accetto
Click on the invia
Now you will get a Grazie! screen. Click the login button. Use the email address and password you just provided.
Then you will be asked for most of the same information again. Remember to put the snc in the N.Civico box.
Click on Continue.
Eventually you'll get to a page where you can click on the visa or mastercard logo to pay. The credit card information is pretty straight forward (even if it is in italian).
And yes, it looks like they ship to the US.
Good luck! I got to the part for payment without issue. I think you'll do fine.
