How “Buy One, Get One” deals work? [Explained]

The price of "one" is typically raised when used as part of a buy one get one free deal. Whilst the cost per item is proportionately cheaper than if bought on its own, it is not actually half price.

But the appeal of BOGO is why it’s hard for consumers to see it for what it is. It’s difficult for consumers to tell whether BOGO is fair or deceptive, and often their judgment is clouded by one four-letter word: free.

Buy one get one free deals are another way of saying " this gadget doesn't work so I'll throw another one in free to ease my conscience".
