I received a free review copy of the vault where I could download 3 themes of my choice. My review is based on that. Well, the catalog is huge. I mean 200+ premium shopify themes. I searched on themeforest for their best sellers and downloaded 3 themes which I found to be useful for my purpose. Pretty happy with them. Considering, a single decent theme can cost $45 or more, this whole deal is a no brainer. Good luck with sales, OP.
