Absolutely, positively, 140% classic military/romance scam. Stop all contact with them now. Not one more reply to them. Block them everywhere.
iTunes cards, prepaid cards count as money, as they can be converted to cash. And asking for money in any amount, even one cent is a scam. Eventually, if you continue they will turn you into a money mule before dumping you. You could also become a victim of a recovery scam or a blackmail scam/sextortion at the end of this romance scam.
There is no real woman. The scammer is a man, abusing stolen photos and videos of an innocent woman.
We need the scammer's DETAILS in order to warn other victims.
Please post the email address used to scam, the name used by the scammer, any emails sent from the scammer to you (remove your name or personal details when posting them,) the phone numbers used by the scammer, pictures sent, documents, ID cards, chat names and IDs, and the name and address of the person that you sent the cards to.
