WooThemes just launched their second iteration, bringing with it several changes, including a website redesign and GPL compliancy on all themes moving forward.
The themes still cost money, but there are no longer any restrictions on how many times you can use the theme you paid for.
Pricing structures have changed, with 2-for-1 and 3-for-1 offers built into the one-time purchases. The “theme club” memberships seem to be a bit cheaper as well.
Also launched now is the new WooCamp blog, which is the theme company’s “design, development, and better blogging outlet.” It might be worth checking out even if you’re not into the premium theme thing…
