To create an opportunity for communication between delivery staff and customers at the door, we set-up a first-time-ever coupon campaign based on the idea 'if you fulfill the unique condition, you can get a discount' and announced it on the website.

From the 1st day of the campaign, it went viral exponentially and created a buzz through SNS. It generated more than 40,000 tweets on launch day and ranked #1 for Yahoo! keyword searches. Moreover, actual delivery scenes were covered extensively on TV, Internet news and SNS. Among 2,925 participants in this campaign as many as 32.9% were new customers.
