I want to buy Norton Security

Hello

My friend who is from Argentina wants to buy Norton security from this website http://lam.norton.com/norton-security-antivirus.

And my cousin, who is Peruvian wants to buy the same product.

I wonder if they both can buy the same  "America Latina Espanol " - Latin America version. or do they actually need to select their actual country.

 

Whenever they finish the transaction with their credit card, the days of the suscription will start running?. Or they can just pay for the product and not installed until their previous version expire.

 

I'm looking for a reply
