Text msg,  Wanted to buy a $50 refrigerator on craigs list with a money order plus $40 to hold the refrigerator until he comes back from out of town trip This of course would be handled by his assistant.  Sure sounds like a scam.

Because it is a scam. $90 for a $50 fridge? Remember that Craigslist & Kijiji are not eBay. No reason to take checks or Paypal. Putting "Cash only, Local only, No texts, In Person" will get rid of 99.9% of the scammers. Cash & carry baby!

Scam.
The way it works:
He pays for the item + extra fund to cover his shipping agent with a bank draft or cashiers check.
He sends you a check, tells you to cash it and send the extra money to his shipping agent via wire transfer or prepaid card.
You cash/deposit check and wire/prepaid the funds to the agent.
Later, the check bounces as it was counterfeit. The money you sent to the agent, who is really the scammer, is unrecoverable due to it being wire transferred/prepaid card.
You are out money and now run the risk of being arrested for passing a counterfeit check.
