I am having a real problem with these posts and the issue. No one here is selling top secret equipment, so what difference does it make who you sell to? As long as their payments clear before you ship the item, where is the problem?
Paypal would be the best payment alternative for selling to someone overseas. That way the funds are in a escrow type account with paypal and there shouldn't be an issue.
Unless the real customer is from a country that we are legally forbidden to do business with, I don't see a problem.
Payments have to clear before I ship and If I was dealing with someone outside the USA, I would definitely use an escrow type of payment service.
Maybe I'm missing something here.
