PeachPay’s integration with YITH WooCommerce Product Add-Ons allows customers to add product add-ons to their orders during checkout, as the name implies. YITH WooCommerce Product Add-Ons lets you capture a higher average order value from your store. But it is PeachPay that increases the likelihood of a conversion happening in the first place. So decrease cart abandonment and increase average order value by using both of these plugins.
