> One of the secrets to improving your conversion rates is removing everything that isn't essential to the checkout process to keep the user on track. We can improve the checkout experience so that, when the user opens the Terms & Conditions page, it will open in a pop-up. There won't be anything that can distract them, and the only thing they can do is close the window. This should improve your conversion rates.
