Theme Solution is providing instant download Themes. You can Download Premium WordPress Themes, Shopify Themes, eCommerce, Joomla, Drupal, WordPress plugins, Blogging templates, and many more for testing purposes.
We won’t encourage you to use any premium theme for commercial use.
All the GPL themes on themesolution are just for testing and study purposes. You have to purchase the theme from the original store like themeforest.net after testing.
