I am a free theme user and despite this I find myself with a very friendly and attentive support service, nothing to say except a big thanks for the team for their work and availability
Passion is their only goal away from financial benefits
I invite you all to support them as you can, buying a theme or at least sharing it doesn't cost you anything
We apply Ecity theme for 2 BigCommerce stores. I like very much the design and the team is always supporting us to customize it according to our needs.
The crew at Webibazaar has been great help when needed! There themes is great and you can tweak them a lot to what you need.
