Costco warns customers about scam coupon on social media

According to Costco, the fake coupons are part of a common scam that circulates in November each year and purports to be a "celebration of the company's anniversary".

"Despite several posts out there, Costco is NOT giving away $75 coupons", it read.

The coupon, which promises users $75 off their purchase is a scam and will not work if used.

Unsolicited electronic communications from Costco do not ask for your personal information such as username, password, credit card information, birth date or Social Security number.

Costco's website also warns of other scams including fake checks, fraudulent phone calls and a fake email campaign that the company is offering them a job.

The store says this isn't the first time this scam has popped up on social media either.

When consumers visited these websites, they were asked to provide personal information for surveys and share the Facebook post in order to redeem the false coupon. Facebook users attempting to claim free products are "victimized by a Facebook 'life-jacking' attack, a malicious script that takes over a user's Facebook profile without their knowledge and propagates itself to their friends' accounts as well".
