WooCommerce makes it so easy to bring your store online to sell your own physical and digital products. With Buy Button, you can add products to your pages, posts, and anywhere else. It creates a simple shortcode for products you would like to promote in your posts.
Users have the option to change background color, text, and other settings for each button. The plugin has a responsive design. All you will need to do is copy/paste the appropriate shortcode.
