I'm in North America, not in Italy.
Answer on Where can I buy Italy Savings Bonds?
why would you want to? then you have to report foreign income on your tax return - what happens if they don't get you the info you need to do your taxes until months after the end of the year? You also will be dealing with exchange rates which could hurt you when it comes time to redeem the bond - you might have to file an Italian tax return - what if their tax rates are higher than US, then you really aren't gaining any benefit
