The key ingredients:
- selling on-line
- buyers from a foreign country
- offering to pay with bank cashier's checks
- wants to pay several thousand dollars more than the asking price, and
- wants you to send back the difference.
At the last minute the buyer asks to send you a cashier's check for $3000 MORE than your asking price, and asks you to send him the difference -- "but only after the cashier's check clears, of course." (Perhaps he explains that someone in the U.S. owes him $7,000 and it would be simpler if that person just sent the cashier's check to you and you sent him the $3,000. Or, perhaps he says he needs the extra dollars for shipping.)
You are skeptical - but, sure enough, the bank cashier's check arrives by Fed Ex, it looks real, your bank accepts the check, and the bank assures you the funds are in fact available. So you wire $3,000 to your buyer in the foreign country and prepare to ship your item.
A week later your bank calls: "We're very sorry, but the cashier's check was counterfeit" -- a superb copy, but worthless. Your account is frozen. You must pay the bank back $7,000. You may even be considered a fraud suspect yourself. Your "buyer" disappears. (About the only good news: sellers rarely get to the point of shipping their car or animals or items abroad.) This scam is cheating people nationwide.
Stay clear of this scam!
