Festive sales 2026: decoding discounts and behavioural nudges behind e-commerce deals

Summary

E-commerce giants use psychological tricks like countdown timers, artificial price inflations, and easy financing to drive impulse buys during festival sales. Experts warn consumers to track price histories and look out for hidden fees on ‘No-Cost EMI’ options before buying.

The annual Indian festive shopping window kicked off with record claims across major e-commerce platforms, with the Amazon Great Indian Festival starting on 8 October and Flipkart's Big Billion Days launching its early access on the same day before opening on 9 October.

“One out of two customers opted for Equated Monthly Instalment financing,” according to Amazon Pay, while Flipkart noted that one in three shoppers selected No-Cost Equated Monthly Instalment (EMI) options.

To make the most of festival sales, shoppers have three types of offers: card-linked instant discounts, credit-linked payment offers, and upfront price cuts. Platforms feature card-linked incentives, such as Amazon’s 10% instant discount on SBI credit cards and Flipkart’s 10% instant savings on Axis and ICICI cards, as well as trade-in exchange bonuses. In addition, No-Cost EMI arrangements offer merchant-funded interest subsidies that reduce the immediate invoice amount.

That said, distinguishing a genuine markdown requires close examination of base prices. Mint’s festive price tracker also showed bargains, such as the Apple iPhone 17e 256 GB on Amazon, which saw a price drop from ₹98,900 on 24 September down to ₹71,999 on sale day, and the Apple 2026 MacBook Air 15-inch (16GB) with M5 Chip on Flipkart, which dropped from ₹1,79,000 to ₹1,59,990. While these sales offer great deals and deep discounts, planners and behavioural experts urge caution, as sale seasons tend to encourage spending beyond planned budgets.

Neuroscience behind the festive nudge

Behind the price-drop banners and flash sales is a framework of behavioural economics designed to capitalize on human psychology. Biju Dominic, chief evangelist at Fractal Analytics and also the author of MicroStimuli: The New Science of Persuasion, points out that platforms actively exploit the contrast principle and scarcity to drive immediate action.

"The most obvious tactic from a festive sale point of view is creating that limited offer or limited period, which is more of a scarcity play," Dominic explained. "They try to create a feeling that this offer is available for a very limited time, so if I don't utilize it now, then this will go away, and loss aversion clearly steps in," he added that visual design plays a central role in establishing price anchors.

"Showing an original price cut off acts as an anchor, and then showing a new lower price relies on the contrast principle as a visual cue that sets in the impression of a deep discount," he noted.
