We generally come across WordPress eCommerce themes that support Woocommerce plugin from WooThemes. Jessica Genesis Theme from Web Savvy Marketing extends this further by adding support for top three eCommerce WordPress solutions: WooCommerce, iThemes Exchange and WP e-Commerce. So, if you install either of these ecommerce plugins – your shop products and content will look just fine while using this theme.
Besides the excellent in-built support for ecommerce plugins, theme itself looks really good. The white background with prominent sections should allow best visitor conversion into sales. There is prominent call to action at top right followed by big featured image section. There are widgets sections at bottom to display: featured products, top rated products and items on sale.
