WooCommerce Terms and Conditions Popup Extension
Also by displaying this pages prominently and accurately, you will increase the confidence in your buyer which will be useful when you are trying to retain your buyers and increase repeat sales. By default, woocommerce gives you option to define your terms and condition page and when customer is at checkout, they are given an opportunity o read this page if they want. But when customer wants to read it, they are being redirected to different page and this breaks your checkout process.
To avoid this WooCommerce Terms and Conditions Pipup extension was created and just after installation, it will show your terms and conditions in popup during checkout process which customer can read and close. When they close it, customer will be on checkout page only so he/she can resume the process. No settings, just install and activate. You are all set.
