Most people assume that a 33 per cent price increase and 33 per cent discount are same; they are not. Let us take an example of, let’s say a dress for Rs 1,500. Now, a 33 per cent discount will bring down the price of the dress to Rs 1,000. But, a 33 per cent mark-up on Rs 1,000 will be actually just Rs 1,330. To get the math clear, a 50 per cent mark-up on Rs 1,000, will get the pricing right. This is where the perception that one is getting a superior discount actually turns the decision to buy financially wrong. I would be happy to buy 33 per cent more chocolates than buying chocolates at 33 per cent discount. Purchase decisions during festive season are mostly based on emotion and for many this is the time for celebrations laced with following one’s values. There is nothing wrong in following these practices, as long as you are not clouded by the real worth or price of the freebie that you may assume is a great buy. Instead of trying mental maths, may be try to work out the maths, and if you feel the seller would have actually lost if the numbers were correct, chances are the deal is not in your favour.
