...and how to avoid it.
What is it?
Retail/auction fraud is the fraudulent practice of not sending purchased goods to online buyers.
Can you give me an example?
"You buy a graphics card on an online website, and receive a small pile of rocks in a box a week later. The graphics card is never delivered to you, and you've just been cheated out of $350."
How can you avoid it?
By using only trusted websites such as Amazon which verify buyers you can make mostly safe online purchases, but if a seller lacks credibility you should always be careful when purchasing goods from them.
