Party game manufacturer Cards Against Humanity made its feelings on discount bonanza Black Friday extremely clear as it offered shoppers the ultimate bargain by selling actual boxes of 'bullsh*t'.

The company replaced all of the products on its website with boxes of cow poo and sold them for $6 (£3.82) each.

Consumers either failed to realise that it was not a joke or a metaphor, or they just have weird needs, as the company sold an astonishing 30,000 boxes of faeces.

It mocked Black Friday on its website, stating that the best way to make a saving is to buy nothing.

The message said: "To help you experience the ultimate savings on Cards Against Humanity this Black Friday, we've removed the game from our store, making it impossible to purchase. Instead, we're offering a once-in-a-lifetime opportunity to buy some new bullsh*t."

When the firm ran out of poo, another announcement was made on the website: "All the poop is gone, you bought all of it. Experience the ultimate savings this Black Friday by purchasing nothing."

CEO Max Temkin told his Twitter following that if they're expecting something instead of cow dung, then they're in for an unpleasant surprise.
