The WooCommerce Cross Sell on Products page adds the ability to cross sell items on the Single Products page.
This plugin comes with the ability to add multiple items to the cart at one time. Cross sell items are listed below the product summary and above the add to cart button.
Each cross sell items is clickable to open a popup window with more product information to help the customer in their shopping.
This is a very useful plug in if you sell a lot of items that need accessories. For example if you sell a cell phone, you can cross sell cases and chargers that you recommend on that same page.
To use it, just install the plugin and then add items to the built in cross sell box that is already in WooCommerce.
