BATAVIA, Ill. -- A major low-cost grocery chain is warning the public of a scam that could leave customers more than a little disappointed.

ALDI USA is reporting that a coupon making its way over the internet is a fake.

"We don't offer electronic coupons and they won't be accepted at our stores," the company said online.

In their post, the company never goes into specifics on the fake coupon itself. However, NBC affiliate WYFF reports that a website posing as an ALDI property offers a $40 coupon for completing a survey. Typically, these types of surveys gather information for less than honest purposes.

And based on what ALDI released, participants in the survey ultimately won't even have anything positive to show for it.

"We're currently working on fixing the situation, but we'd love your help," the company posted.

The best way to do that: spread the word that these online coupons are phonies.

ALDI, a German company, currently operates more than 1,600 stores across the U.S.
