Free Shipping Bar shows a progress bar that tells shoppers how much more to spend for free shipping, and celebrates when they get there. It reads the cart in the browser, so it updates instantly and adds no requests to page loads. Set your threshold once and it converts to every currency, or set your own per currency. On Pro, suggest products from the cart page that close the gap, and match the bar to your brand colors.
