I too was trying to sell something and the person was trying to do this. Person's email claims to be
[email protected] ( typical American name) but wanted me to ship Express mail, which takes 2 days to his brother with a definate Indian/ Arab name in Nigeria. Person was texting me info. and very insistant that I hurry up and sent pay pal. I contacted Paypal and they said account not set up for this person but could be, but they have to verify and this could take several business days. They could be paying with stolen card and too many frauds sent to Nigeria. Postal service said I would have no recourse if they claimed item stolen or never made it there and they could get back money from Paypal etc.
I offered to ship to US city at my expense and they could ship to the brother. Oh no... they didn't have time to do that.
