Another scam is making the rounds, says Missouri Attorney General Jay Nixon in the Springfield Business Journal. His office 
is checking a report from a resident who "answered a ‘secret shopper’ newspaper ad" with the promise of "cash and merchandise in exchange for evaluating customer service at retailers."
The woman "received a money order for $1,300 and was instructed to keep $100 and wire the remaining funds to an address in Canada." The money order, of course, was bogus.
"Con artists are increasingly using fake, but realistic-looking, money orders as part of their scams," Nixon said.
If someone you don’t know asks you to send them money "to cover fees, taxes or anything else," says Nixon, "it’s a big red flag that it’s a scam."
If someone you don’t know asks you to send them money because they sent you money, do not do it. Why is this so hard?
