YITH WooCommerce Product Add-Ons Extra Options

The ultimate tool to add options and extra services (free or paid) to your products and offer them to your users
WooCommerce allows selling any type of product and lets users choose simple variations, like size and color.
Yet, this is not enough. If you sell your products online, you most likely need more advanced options. For example, if you sell rings or jewelry, you might need to let your customers add a custom text to be engraved in a piece of jewelry or choose carats for a gemstone, the size, the color for gold.
