Along with signaling the end of summer and the beginning of fall, the arrival of September also means an onslaught of tasteless 9/11 advertising.

The most recent offender is this commercial from a San Antonio mattress store, which was posted on the Miracle Mattress Facebook page earlier this week, and then deleted after receiving intense social media backlash.

According to My San Antonio, the ad shows "manager Cherise Bonanno and two employees boasting the promotion in front of two stacks of mattresses."

If you think naming a deal the "Twin Tower sale" is bad, it gets worse.

The store owner has issued a lengthy apology, expressing “sincere regret: the video is tasteless and an affront to the men and women who lost their lives on 9/11,” reports BuzzFeed.

While this commercial's co-opting of 9/11 is pretty egregious, this is not an isolated incident — brands have been exploiting 9/11 for years.

This week, a Walmart store in Florida faced similar outrage for its display of Coke boxes in the form of the Twin Towers in front of a design of the U.S. flag.

As BuzzFeed previously noted, companies have used the tragic events of 9/11 to promote awareness regarding everything from the dangers of smoking to the brutality of tsunamis.

But nothing gets backlash quite like a 9/11 campaign with a good ol' capitalist thrust behind it. The Walmart display inspired The Washington Post to revisit the tacky practice of using 9/11 to market consumer goods and how it consistently backfires.
