The WooCommerce Flying Cart plugin includes an icon that lets you open the cart popup and show the cart contents at any time. The icon floats on the page, meaning that it will always be available in the same position on the screen even if you scroll the page up or down or if you move from one page to the other. If you are browsing the website or reading more about a product, you will be able to check and change your cart contents at any time with just one click.
