In order to increase trial on Clickshop.ro, a newly launched e-shop by Romtelecom, we launched an online promotion which encouraged people to subscribe to Clickshop's newsletter in order to win the biggest discount ever seen: 99%. We created a microsite featuring a huge green button, which you had to click several times in order to find out how the campaign works. (The catch-phrase "Click me" was very popular in Romania at that time.) The final click got you subscribed to the newsletter and into the competition.
As part of a Facebook teasing campaign, we transformed famous number-based movies/books etc. to star the number 99, asking the question "What's 99? Find out on 25th October."
