This whole thing is a scam!!!. I searched for a website and the only thing close to Market Links is a Bulgarian business website which is close but has no affiliation to the U.S. for a mystery shopper or consumer service evaluator. After not finding a definite connection I called the bank the $3, 530.00 check was drawn from and was told flat out 'DO NOT DEPOSIT THE CHECK, It's a scam.'
If you get any large check to be a mystery shopper or a consumer service evaluator, don't deposit the check like it says and wire them money back to 'Evaluate the effectiveness and efficiency of the payment system Moneygram.' Even though the letter you receive with the check and the survey looks legit and professional, It is not.
All you need to do is call the Bank that is listed on the check- Google the name to get a customer service number and give them a call. They will tell you the same thing they told me- IT'S A SCAM. Tear it up and save yourself your hard earned money.
