thats the classic BS scam message, just ignore.
this is one i got a while ago.
"Hello,
I really appreciate your response to my email.I want you to consider
it sold, pls do withdraw the advert from craigslist to avoid
disturbance.I want you to know that i will be paying via bank Cashier
check .I will like you to provide me with the following. information
to facilitate the mailing of the check to you .
1.....Full name to write on the check
2.....Full Physical address to post the check
3.....City, State and Zip Code
4.....Home & Cell Phone to contact you
*** Note that the payment will be shipped to your address via UPS NEXT
DAY SERVICE and I will like you to know that you will not be
responsible for shipping i will have my mover come over as soon as you
have cashed the check** Thanks
Please get back to me asap. Also i will like you to remove the items
form the sales board Thanks."
That or any variation on it is BS 100% of the time.
-Good luck with your sale bro.
