If you need more time to brainstorm with creatives and receive additional entries, you can add more days to your contest. You are allowed to add up to 5 days to your contest. Each additional day costs $25. For example, if you decided to add 3 additional days to your existing contest, you would need to pay $75.
In order to extend your contest, go to your Contest Dashboard, and click on "Add More Days" on the right side.
Please note that you have upto 30 days to select a winner for your contest. You only need to pay if you are adding additional time to extend your "name-creation" phase where you receive entries from the creatives.
