The new Product Add-Ons extension allows you to add additional data fields to your individual product pages. That means you can add any field with a custom text title, and then allow customers to respond via a checkbox, select box or text input.
So, for example, you may wish to allow customers to pick from a list of optional upgrades or accessories for a particular product, along with options to add custom text and personalisation.
You can also set individual prices for each option, giving you a great way to up-sell to your customers as part of their initial purchase and not disrupt them during the checkout process.
Please note: For the Product Add-Ons extension to function, you’ll need to have installed the latest version of Jigoshop, which is available to download via your WordPress Admin Dashboard if you have Jigoshop already installed, or from WordPress.org if you prefer to install the update manually.
