I agree. This is a scam. I have got dozens of similar type emails when I was trying to sell a car on the internet. Same scam, poorly written emails. They want to send you the check(s) via courier so as to avoid postal fraud also. (I only give out a PO box for cases like this). Ask them for the bank/account numbers of the check and for detailed buyers information if you want to ?play along? some. (If they give it to you, contact the FBI). Usually, they quickly disappear after to get inquisitive.
