Beware of email messages where the sender requests a print/s then goes on to say they will deposit a cheque in your bank which will be released on delivery. Sometimes they will deposit a cheque made out to double the required amount, then they will ask you to send them the overstated amount because their accounts dept made a mistake. These scammers choose any service or product offered on-line. They will be from another country and the cheque will come from a small unheard of bank.
This type of scam is pretty obvious, but people have been taken in! if you receive this sort of message trash it or proceed with caution, if your bank is on the ball they will alert you if an unusually large cheque arrives from an obscure overseas bank.
