I got a weird email from a foreign person in response to my classified ad

It has come to our attention that some scammers are sending messages to people who've posted a Boreal classified ad.  These scammers will contact you and say they're interested in buying your item.  They want to send you a check, cashier's check or money order for more than the selling price, and have you send the extra money back to them.  Usually this is a foreign person so the check or money order is drawn on a foreign bank.

If you receive this type of message, DO NOT RESPOND!  This is a scam!  NO LEGITIMATE BUYER does business this way!  After you send the extra money back to this person, the original check will bounce, and you'll end up owing the bank the money you sent to the scammer.

Remember, although your bank will make funds available to you within a few days (they're required to by law) it can take 4 OR MORE WEEKS for a foreign check or money order to clear the issuing bank, so it will be that long before you find out the original check was bad.  Money orders  and cashier's checks can be bad, too - a person can use a rubber check or stolen credit card to buy a money order or cashier's check, and once that check bounces so will your money order / cashier's check.
