The WooCommerce Flying Cart plugin includes an icon that allows you to open the cart popup and view the contents of the cart at any time. The icon floats on the page, which means it will always be available in the same position on the screen regardless of whether you scroll up or down the page or move from one page to the next. If you are browsing the website or reading more about a product, you will be able to check and change the contents of your cart with a single click at any time.
