The secret shopper scam is one of the oldest online. There are not any legitimate companies that will send you an email that ask you to be a secret shopper WITHOUT knowing Your name and address. If they were legit, they would already have your name and address. Always pay attention to how Your email is addressed. If it is addressed without any mention of Your name, You can know right away it is a scam or if it is addressed to dear friend or something silly like that. And be sure that any legitimate company would always have a website, real email address (not aol, gmail, msn, etc..) and a real American address which you could look up. The purpose of the email is to steal Your identity, do not provide them any information.

This one is from Jason Vaughn but you might get one from any name:
