Tyche is one of the most popular free WordPress eCommerce themes in the market from Colorlib. Although it’s a free theme, it provides you with premium features and professional design of a pro theme. You can turn your website into a stunning store and sell anything with WooCommerce, or set up your contact page, Google map site to make it easy for your customers to follow you.
With a tone of recommended plugins compatibility, you can have more interesting features to make your website outstanding. Especially, the demo content can be imported quickly and easily to your website so that you can have a foundation to set up your store.
To recap, this feature-rich free eCommerce theme worths a thump up with a professional design and interesting features. However, it's not totally ready for SEO yet and I still find some mistake when customizing this theme.
