As far As I am aware the Pacsafe card is a way that people who cannot get a credit card can pay online. Or can be used for people who do not want a paper trail of a transaction. I also do not think you would have the clawback options as you would with PayPal or credit card. One would suspect that once the money is passed over it would not be returnable. Therefore I would suggest proceeding with caution and treating as a scam.
