Don't get ripped off on Craiglist

Buying and selling on Internet classified sites such as Craigslist can be a great way to find a deal and make extra cash. But it can also expose you to a host of scams.

Here are some tips to help keep you from being ripped off:

Meet up: Meet the other party in person. By following this single rule, according to Craigslist, you will avoid 99 percent of attempted scams on the site.

Any time the other party is unable or unwilling to meet face to face, it should be a huge red flag.

Money mistake: Never wire money to the other party. If you do make a deal with someone far away, don't pay through Western Union or a similar service. "Anyone who asks you to do so is a scammer," Craigslist warns.

No guarantee: Remember, Craigslist does not guarantee transactions, "certify" buyers or sellers, or protect payments in any way. If someone says Craigslist will do so, they're probably trying to deceive you.

Some scammers will send an official-looking email, appearing to come from Craigslist, saying that the site will guarantee the transaction. Don't believe it.

Fake check: Watch out for overpayments. An all-too-common ruse is for sellers to be sent a "bank check" for more than the selling price, with a request for the balance to be returned. If this happens, you can be sure the check is a fake.

Eyes on: See things for yourself. Don't rent an apartment or house without viewing the inside, and don't buy something expensive without seeing it with your own eyes. If the other party balks, Craigslist says, "in all likelihood that housing unit is not actually for rent and that cheap item does not exist."
