I got the same email also. So I responded and this is what I got back from him and it seemed kind of shady.:
Hello
Thanks you very much for your urgent response, i will like you to mail me the pics, and i have relay it to my client and is very interested in buying it, and i have already explained everything to him about the System and he wants to pay the amount you charged on it
He now requested for your Full Name and Address with your Phone Number so that he can make the check for you.because he is paying with a Money Order OR cashier's check which will easy to cash at your Bank.
And i will also arrange for the shipping agent who will come for the picking up at your house.when the check clears.
thanks for your co-operation
