When contacting a seller, ask if they accept cash and F2F first. If they say no, they are a scammer. Move on, they will take your money.
I am not a seller.
Yes
Check out "Westgreens" in Hoxton Park, 2171 NSW, to see what a legit seller looks like.
Sellers who want money upfront are scammers. Legit sellers will ONLY do face to face (F2F) and ONLY accept cash. Beware there are a LOT of scammers.
