Hi i’ve looked at the comments on the theme page of Themeforest, and you said this 2 years ago.

Unfortunately, at this moment, the theme is only compatible with the woocommerce plugin, without any major customizations or changes at code level to change the woocommerce functionality. We only change the style of the plugin to be in according with the theme design and also added some settings in Theme panel for the custom sidebar and sidebar position.

In the next period, we will concentrate to add better integration with woocommerce and extend shop’s functionality, we’ll add invoice and package label generator and interactive basket as well as other cool features. Until then you can try a plugin to add the shopping cart or try to add it yourself.

You simply have not done this and to say you will is actually misleading and from what I can see adding the functionality is quite simple from a code point of view. Why could you just not include it?

You just don’t seem to be delivering on what you promise and most other themes are.
