John Day posted an Amazon USB fan ad on the Latest Deals Facebook group.
But instead of a photo of the fan, the ad, which has since been deleted, included a photo of a sex toy.
Although a description of the USB fan has been included, a pink vibrator with a satisfied woman can be seen in the lower corner.
The 55-year-old captioned the blunder: “Question. How is that going to keep me cool? I just don’t understand how it works? “
His post quickly went viral, garnering hundreds of likes from other savers.
One of them commented: “Guaranteed to make you hotter, I would have said.”
Another added: “Is there a direct link? Ask a friend.
While a third wrote, “Not a bad price,” accompanied by a laughing emoji.
And a fourth said: “I have all my Amazon packages delivered to my parents.
“They open the majority of them because they are gifts / good deals from here. I should order this.
John told Latest Deals: “I use the Facebook group daily and thanks to the network of other members, I find many great offers. I’m going to get mine and with this hot weather that we have, like a lot of people, I was looking for ways to stay cool.
“On this occasion, Amazon UK showed me something that I might like about the things I was looking for. As you can see the image caught my eye and after investigation it turned out that it It was a USB desktop fan.
“I posted the link on the group and waited for a response from others… and to say the least, I’ve never seen so many likes on a post and haven’t laughed so much at the responses.”
Tom Church, co-founder of the Money Saving website, said: “It’s a hilarious mistake, but Amazon may not be at fault.
“Usually the merchants on Amazon upload the photos, so the seller made a little mistake.
“It looks like the problem has been resolved, but I’m wondering if anyone ordered a fan and got a vibrator instead.”
According to an Amazon spokesperson, who confirmed to Daily Star Online, it was a third-party product that was not sold by the retailer.
