Yes! We encourage you to self-launch non-winning challenge submissions to your Store. Once winners have been announced for a challenge, there's no need to wait for the Trial Period to end - you're welcome to self-launch your non-winning pieces to Minted right away. There's always so much more great work in every challenge than we can accept as winners, and we love seeing these pieces find homes in your Stores!
PLEASE NOTE: Work submitted to challenges is still subject to the 90 day trial period in that you may not publish it elsewhere until 90 days are up, even if you do not make your product exclusive to Minted.
