There are thousands of free WordPress themes out there, but if you want your blog to stand out from the crowd you probably want something more, something nicer than what’s available for free and depending on your needs, you may not be willing to pay for a custom theme since it can be quite expensive (though it’s still one of the best options if you want to really stand out!)
So here are 17 Premium WordPress theme stores, I’m sure you’ll find something you’ll like! And most of them offer developer’s licenses too! Very nice if you have many clients that are in need of WordPress blogs.
