HOW TO AVOID BUYING FAKE GOODS (luxury goods & high street)

Recently, a friend of mine sent me the pictures of the items she ordered from a seller online; when she got the items, the pieces she saw in the photos were not what she received in person. Holy crap right? She was tricked into buying rubbish / fake. She is not the only one, a lot of people have fallen into this trap of fraud where they buy things from online scammers who steal photos from reputable brands to sell their products.
