A good plugin stack makes the difference between a site that performs and one that creaks. A bloated one creates security risks, slows load times, and costs more than it should. This category covers the plugins worth paying for — WP Rocket, WooCommerce extensions, SEO tools, form builders, and security plugins — when they are discounted.
No plugin is featured here unless I would install it on a client site. No deal is listed unless the price represents genuine value.
