Received a cheque in the mail today, is this suspicious?

If you do not have a bank account with the bank it's highly unprobable they will cash it, because if they do and the check bounces or is no good then you are resposible for paying the bank back. Or perhaps the check is good then they send you another asking you to send them some money back from it because they can't cash checks in your country. You do this and then the check is bad and you are alos responsible. Do not fall for this it's so easy, remember if it sound too good to be true, then it is.
