Never think that a scam is something where you will be cheated of your money and get nothing in return. A scam can also be something wherein you pay extraordinarily high for an ordinary thing. And this scam can happen right at your doorstep as it does in Western Australia.
Students come to your doorsteps selling beautiful hand paintings. They tell you that they are doing this to make their ends meet. You are impressed. You give them the money and buy the painting without questions. You later come to realize that you paid $600 for a painting worth nothing more than $5. This scam has been going rounds in Western Australia for a long time. It has now become active in the United States and Canada too.
There is no way to escape from this scam but to avoid buying paintings from people at your doorstep.
