Power discounts often enhance consumer spending and that became apparent to me on a recent visit to Delhi. An aunt of mine decided to travel nearly 25 kilometers in a DTC (Delhi Transport Corporation) bus to have lunch in a restaurant in Connaught Place, which was offering a 20 per cent discount. And this was a time when the heat in Delhi was killing, with the temperature being greater than 40 degree Celsius.
After coming back to Mumbai, I heard about a high-end lifestyle brand putting its goods on sale. And women queued up for it from 6.30 in the morning, despite the heavy rains. That’s the power the words discount and sale have on the human mind. They can really get people out there to shop, despite the rains and the heat.
In fact, Eric Anderson and Duncan Simester carried out an experiment to test whether just labeling something to be “on sale” lead to higher sales. Jonah Berger discusses this experiment in his book, Contagious -- Why Things Catch on. As he writes, “Anderson and Simester, created two different versions of the catalogue and mailed each to more than fifty thousand people. In one version some of the products (let’s call them dresses) were marked with signs that said “Pre-Season SALE.” In other version, the dresses were not marked as on sale.”
The results were very interesting. The items on which a sale sign had been marked, saw the demand go up by more than 50 per cent. “The prices of the dresses (the items marked to be on sale) were the same in both versions of the catalogue. So using the word ‘Sale’ beside a price increased sales even though the price itself stayed the same.”
While just mention of the world ‘sale’ is likely to increase sales, the trick is not to overuse it. As Anderson and Simester point out in a research paper titled The Role of Sale Signs, “If customers’ price expectations are sensitive to the number of products that have sale signs, this strategy is not without cost. Using additional sale signs may reduce demand for other products that already have sale signs.” Also, if a product is always on sale then there is a problem because people can’t compare it with anything.
Despite these negatives, the fact is that everyone wants a good deal. In fact such is people’s fascination for getting a good deal that in some cases they are even willing to pay more.
Berger carried out a small experiment in which a barbecue grill is on sale. Originally priced at $350, now its being sold at $250, a saving of $100. He ran this ‘deal’ through 100 people and 75 per cent of the people said that they would buy the grill. There was another scenario in which the same grill was on sale but at a different store. Originally it had been priced at $255 and was now selling at $240. Berger ran this ‘deal’ through 100 people and only 22 per cent of the people said they would buy the grill.
And this is what made things really interesting. “Both stores were selling the same grill. So if anything, people should have been more likely to say they would buy it at the store where the price was lower.... More people said they would purchase the grill in scenario A (the first scenario where a $350 grill was being sold for $250), even though they would have to pay a higher price ($250 rather than $240) to get it,” writes Berger. Discount and sales offers play tricks on the human mind leading it to make irrational decisions, which are exploited by marketers. Akshay Rao of the University of Minnesota carried out a research on discounts and offering something extra for the same price, which he published in a paper titled, “When More Is Less: The Impact of Base Value Neglect on Consumer Preferences for Bonus Packs over Price Discounts”.
In this paper, Rao came to the conclusion that “shoppers prefer getting something extra free to getting something cheaper.” He explains this through an example of coffee beans. On a normal day, 100 coffee beans are being sold for Rs 100. One day, a discount of 33 per cent is on offer. This means 100 coffee beans are sold for Rs 67.
Another day, a 50 per cent extra offer is on. This means 150 coffee beans can now be bought for Rs 100. But what this also means is that 100 coffee beans can be bought for Rs 67. So a 33 per cent discount offer and a 50 per cent extra offer are economically equivalent. There is no difference between them, at least theoretically. But real life turned out to be different from theory as usual. Rao and his team carried out an experiment and found that they managed to increase sales of a consumer packed good by over 70 per cent in a retail store, when they used the extra/free bonus pack format in comparison to offering a discount on the product. Rao attributes this to the fact that the human mind is not good at performing arithmetic with complex forms such as logarithms, fractions, probability and percentages.
So if you have ever wondered why everyone from biscuit companies to mobile phone operators wants to give out something extra, rather than offer a discount, you now know why.
The inability to handle basic math leads to marketers exploiting it in other ways as well. One such way is to express discount in a way where it seems larger than it actually is. As Berger writes, “20 per cent off on that $25 shirt seems like a better deal than $5 off. For high-priced big-ticket-items, framing price reductions in dollar terms (rather than percentage terms) makes them seem like a better offer. The laptop seems like a better deal when it is $200 off rather than 10 per cent off.”
Whether marketers express discount in absolute terms or in percentage terms depends on the rule of 100. If the price of a product is less than $100 (or Rs 100 or any other currency) the percentage discount will seem bigger. Vice versa is true, if the price is higher than $100. “For a $30 shirt, even a $3 discount is still a relatively small number. But percentage wise (10 per cent), that same discount looks much bigger... Take a $750 vacation package or the $2,000 laptop. While a 10 per cent discount may seem like a relatively small number, it immediately seems much bigger when translated into dollars ($75 or $200),” writes Berger.
The interesting thing is that the rule of 100 doesn’t seem to have caught on in India as yet. This could be a killer application for discount websites, which still focus on expressing discounts in percentage terms. As I write this column, the Bangla version of Amish’s “The Immortals of Melhua” is selling for Rs 130, a 33 per cent discount on a price of Rs 195, on one of the discount websites. Now wouldn’t Rs 65 off have sounded so much more better?
While marketers are quick to latch on to these tricks, in this case they seem to have missed out on something rather obvious. Rest assured this anomaly will be corrected in the days to come.
