There are so many premium themes out there, at such a low price that you’re just forbidden to have an ugly website anymore. More and more online companies start selling awesome wordpress themes, and, along with this raise in premium theme services, as a way to get more customers (or just for generating traffic and then selling advertising), some of these companies are offering free premium themes, and I must admit: gorgeous themes these are!
You could take a look at free premium themes since 2007 and you will observe how much things have evolved. We have now awesome designs and the choice to use them free of charge! Of course, chances are that more people will use a free theme than a paid premium one, but you still can customize it a little bit to express your own online personality.
