In the first sentence of the email you can tell it's a scam right away, *hint* "I will buy this item from you".....lol....what kind of buyer would declare that in the first line of his email, without asking any legit questions?? Not only that, it sounds FOREIGN. I would have deleted this before going further. I now know how so many get scammed over the internet.....
Not only that, but he wanted your zip code and state.
