Our module's capabilities go far beyond what is available via either the native shipping capabilities of OpenCart shipping options or the other available plugins. While most shipping plugins can sometimes adequately handle simple shipping situations for simple items, they quickly break down when working with multiple items or quantities-- let alone any other complexities.  In particular, our plugin utilizes your item dimensions to generate accurate rates-- a necessity,, as all carriers now use package size as a critical component to determine rates.
