How can you tell?

[kala]

I know that there are certain sites that are legit. These are the sites I visit most often to make my online purchases. If I am going to be looking for something that isn't available on my regular sites, how do I know if the site is a scam. What can be done if you are a victim of online fraud?

that's a difficult one, I don't know how to tell myself
