One of the most undesirable “buy one, get one free” sales might be for items that are not typically needed in multiples or have long-lasting negative consequences. Take, for instance, a “buy one, get one free” offer on coffin purchases. Given that most people don’t plan to ‘use’ a coffin more than once, acquiring an extra one doesn’t provide additional value or utility. Moreover, coffins are associated with sensitive events like funerals, which typically aren’t occasions where marketing tactics like sales bring much cheer.
Another example could be for items that pose a health or safety risk. For instance, a “buy one, get one free” deal on expired pharmaceuticals or toxic substances, like harmful chemicals, would not only be impractical but also potentially dangerous. It’s important to remember that appealing offers like “buy one, get one free” are typically only beneficial when the items in question are desirable, safe, and needed in more than one quantity.
