I love the variation of sites that can be created with this. I'm still struggling to get the multi-vendor site
For multivendor sites use redokan, remarket, redirect demo. To be truth, all our demos can be used for multivendor. You just need to install one of compatible multivendor plugin (most popular are supported)
Also, our blog has full guideline for multivendor sites
I bought this theme some time ago and I've started to use it now in a project, I'm used to work a lot with Themeforest themes and I'm really surprised with the quality of the Re:Hub code and its fast learning curve. It's worth giving a 10 to the provider and our buying support for constantly updating and maintaining the quality level. Congratulations.
