Publix is warning customers that there’s a fake coupon floating around online.

If you spot it, the company says not to save it or try to use it.

The grocery chain’s Twitter account posted a photo of the fake coupon, which offers $75 off a purchase of $80 or more. As the old saying goes, if it sounds too good to be true, it probably is.

The company posted a longer statement on its Facebook page, saying, “There is a fraudulent Publix coupon circulating on social media that states “$75 off your purchase of $80 or more.” This is not supported by Publix and this coupon is not valid at any of our locations. We recommend not participating in the promotion or providing your personal information. Thank you for your patience as we investigate this situation.”

The coupon stems from a supposed promotion for the company’s 89th anniversary. It’s being shared by many people on Facebook. A recent similar post promised an Aldi coupon in exchange for an email address and sharing a post on Facebook. However, that also proved to be a scam.

This isn't the first time Publix has had to deal with fake coupons. Last summer, a similar incident occurred.
