The Better Business Bureau of Acadiana says you should be wary of offers for promotional coupons on Facebook. That hundred dollar coupon offer may be a scam out trolling for personal information. Many times the scam uses a real business logo lifted from an official website. The BBB reminds you not to take the bait if it sounds too good to be true and confirm before you trust your 'friends' online. Their accounts may have been hacked. Report suspect social media posts to the social media company such as Facebook or Twitter.
