Be careful buying things from people on this site who have a very low post record.
Scammers have recently infiltrated here, they take your money and send you nothing.
If you check the post history of the first person that responded you will see that every one of his post are "Yes I have that for sale" no matter what part is being talked about. This is red flag for sure, hopefully you did not email this person, chances are they are a scammer.
The next person that contacted you only has the one post, so it is likely the scammer starting a new profile.
In the last 6 months or so every time someone posts up for sale or wanted these clowns post up fraudulent responses. They will also PM you . Do not fall for this crap. Moderators, is there nothing you can do about this?
