Delhi-based second-hand automobile marketplace, Droom, started selling ISI certified helmets for Rs 9 one day every month since January 2017. Droom intends to reap the benefits of this campaign later by cross-selling second-hand two-wheeler and four-wheeler to the customers.

The Maximum Retail Price of the ISI Tagged helmets is Rs 750. However using Droom coupon code, you'll be able to order them at Rs 9 on Droom.in. This is a part of customer advocacy campaign.

They've managed to sell more than 50,000 helmets. The people used the Droom coupons and have Safe helmets at lower cost and happier faces ;)
