I am not sure if I dodged a bullet or not.
When the AlienLawnCare asked me to ship him this item, he requested paypal to pay me and the full payment did come through. As I was getting ready to ship it the following evening, I get another email from paypal saying it is now being disputed.
According to the status details on paypal, it says "The buyer has filed a claim stating this transaction was made without the account holder’s knowledge or consent".
I have contacted paypal and they advised me not to ship the item (I am glad I was not too quick to ship). I asked paypal if this was some sort of scam and they said that they are investigating.
