We have been alerted by two of our advertisers to a scam which is currently doing the rounds. In each case the potential buyer agrees to buy an item and then sends a cheque in payment. However the cheque is for more than the asking price of the item. The ‘buyer’ then asks the seller to refund the difference. Because it sometimes takes a week or more for the bank to process a cheque, it can be some time before the seller realises the cheque has bounced.
