SCAM. I also got the $2880 check with the same instructions.  Yellowsurveys.com sent this!  BEWARE!!

This is definitely a scam.  I received the letter with the "cashiers check" and was suspicious.  I did some research and found some similar examples of the scam.  Apparantley you are supposed to cash the check at your bank (mine was for $2,880) then wire $2,500 to Canada.  You get to keep $300 for your troubles and there is an $80.00 service fee.  This is your "training" assignment, then you will be a secret shopper and receive various assignments...free money!!!!  The problem is the check is a fake.  Once you cash the check you have 48 hours to wire the money.  So you wire the $2500 dollars before your bank realizes it's a fake.  Since the check doesn't clear you are responsible for the money, but since you have already wired the $2,500...you're basically screwed.

This is not a call that came in but a phone # listed on a scam.  I received the letter and fake cashiers check in the mail. Another phone # listed on the document is 647-686-8691
