First of all , what products do you sell?
Dont trust any buyers from Nigeria, period.
This is how they scam you. They send out a fake but real looking check, either by western union, a check, or a money order.
You send out the products, you cash the check to realise its fake; its too late your goods are gone.
There has also been some cases where you were able to cash the check, then weeks later you are notified from your bank that it was a fake, so they charge you..
So just dont do any business with these people.
If you want more info, goto google and type in nigerian scam, youll get thousands of hits.
