Woostify theme has been built with good functionality which is required for an eCommerce website. That is why I have opted for woostify pro. If we purchase any theme or plugin main thing matter is the support. How they are resolving the issue related to the theme or plugin? When it comes to woostify pro support. am very impressed with their support. Till now I have built 2 websites using woostify pro. While building the website I got any issues I will reply to them. They resolve issues asap. I am really impressed with the support that I have 8 more woostify pro licences. If I get any client related to an eCommerce store. I will strongly suggest them woostify pro. If you are thinking to purchase or use a free theme just go for it. It's worth trying.
