and when you get them shipped to you from online they still have to cross the boarder, possibly get inspected and confiscated and you still get in trouble...

and its zero risk to the shipper if their in another country, whether their sending real ones or fakes...
its not illegal for them to buy them or sell them...
its illegal for you to buy/posses them...

and if you get fakes... what are you gonna do, report that their selling fake cubans to the better business bureau?
