In your hurry to buy something for Mom this Sunday, be careful not to fall for a Mother's Day Facebook scam that could steal your financial information and even your identity.

Several states and the Better Business Bureau have issued warnings about scammers using Facebook and other social media to offer free Mother's Day coupons for discounts of $50 or more from major retail chains, including Bed Bath & Beyond and Lowe's.

The fake coupons contain links that take Facebook users to a phony website, where they're asked to fill out a survey. That survey may be an attempt to steal personal information, such as your email address, telephone number, date of birth, and credit card information, according to the fact-checking website Snopes.com. Recipients are also asked to forward the coupon to their Facebook friends.

"The coupons may never arrive and are worthless anyway, but the private information you provide when filling out the survey is valuable to the crooks," says the North Carolina Attorney General's Office in an alert.

Bed Bath & Beyond issued a notice on its Facebook page about the scam, advising consumers that the $75 coupon for its store is fake. "We are sorry for any confusion and disappointment this fake coupon has caused. We are partnering with Facebook to have these coupons removed," the message says.

The Better Business Bureau has reported a similar Mother's Day Facebook scam offering a $50 coupon for Lowe's

Other coupon scams in the past targeted Home Depot, Costco, Amazon, and Kroger shoppers, reports Snopes.

Katherine Hutt, spokesperson for the Better Business Bureau, warns consumers to be on guard against coupon scams and other fraud on social media. "Facebook and other social media channels don't screen for truthfulness," she says. But Hutt says they are usually quick to remove the fake coupons once they're notified.

The BBB says social media scams may use the colors, logos, or other authentic-appearing details from Facebook pages or other websites. Links and email from social media sites also can be faked, it says. The BBB notes that for legitimate coupons or other giveaways, businesses don't request credit card numbers or banking information.

If in doubt about whether an offer is real, the BBB advises trying to search for it on the web. If it's a scam, you may turn up an alert. You also can go directly to an organization's or retailer's website, which may have information revealing whether an offer is real or a fraud.
