Department of Consumer Affairs warned consumers against ‘Dark Pattern Drip Pricing’ on E-commerce platforms on Thursday via a post on social media platform ‘X’. ‘Drip pricing’ refers to hidden costs that accumulate in the end to cause a spike in the check out amount.

Authorities highlighted that customers can also check for the hidden price and the National Consumer Helpline offers a service to raise a complaint against platforms for these practices. The drip pricing inflates the final bill even after a discount.

“The deal looks great at first, but hidden charges at the end hike up the price — that’s Drip Pricing, a Dark Pattern!”, the caption of the post read.

The government’s warning comes in the backdrop of robust e-commerce festive sales during the Diwali stretch. Along with the warning Consumer Affairs department also shared a helpline number for those who notice these hidden costs and drip pricing, the helpline number is — 1915.

The e-commerce sector noted a sparkling 24% year-on-year growth in order volumes and a 23% surge in gross merchandise value (GMV), at the end of Diwali Season 2025, as per Unicommerce, the e-commerce enablement SaaS platform.

As per the release, “The 2025 Diwali festive season ended on a strong note for India’s e-commerce sector, which recorded a 24% year-on-year (YoY) growth in order volumes and a 23% rise in gross merchandise value (GMV),” as per Unicommerce release.

Quick commerce apps emerged as the biggest growth driver, clinching a 120% year-on-year jump in order volumes, followed by brand websites with a 33% rise.
