Kijiji Purchase Scam

The victim placed an ad on Kijiji and lists the price. He then received a response from an interested party and an agreement to purchase is made and the ad is removed from Kijiji. The cheque for payment was then shipped only to have the scammer email a short time later saying the office staff had made a clerical error and there was an overpayment on the cheque sent and asked the victim to cash the cheque and ship the scammer back the difference. At this point the victim became suspicious and contacted the police and the cheque was learned to be counterfeit. Had the cheque been cashed at the bank and the money sent the victim would have been at a loss for the item on Kijiji, the amount of the cheque and the difference sent back to the scammer.
