Currently my styles are among the most expensive styles for XenForo. That did make sense when my styles were the only ones with responsive design, which was long time ago, but not anymore. As of tomorrow all XenForo styles based on my custom framework (all my styles, except for Soft Responsive and Black Responsive) will cost $29 (down from $39) to bring it in line with pricing of competing products. This does not mean however that development has halted. During last couple of months my styles have evolved, currently all styles have huge amount of custom style properties (latest versions have over 700 custom style properties), several preconfigured layout options and many unique features.
