We’ve challenged four of our top selling theme designers to our first-ever Theme Throwdown.  Each theme designer gets to choose five of their top-selling themes, one for each day (Mon-Fri), for a week of Deal of the Day promotions. Whoever sells the most  themes in their week wins the “Theme Throwdown Champion 2010” title.  The cool thing is that each featured theme is 50% off the regular price.

To help get the word out about the Theme Throwdown we’ve created a Twitter contest.  All you have to do for a chance to win 10 free themes from your favorite theme designer is ReTweet the following Tweet.
