Hi Amanda,
We use to have 3 types of competitions on CakesDecor:
1. Quarterly Awards – you can find the link on the top(Awards) and there is also a countdown located on the top of the home page If there is currently running one. Next Awards will start on April 1st
2. Facebook giveaways – we launch them from time to time. There is an album on our facebook called Giveaways where you can find previous giveaways.
3. Contests – we launch them from time to time. I’m the one who always announce them, so feel free to check my Blog Entries for previous contests.
Usually, there is a banner on home page referring to the contest.
Here you can find the current contest.
