MiniCart is a great way to improve your PayPal shopping cart integration. Your users will be able to manage their shopping cart directly from your website. This extension is based on Jeff Harrell's minicart.js: http://minicartjs.com/
This extension works in combination with the standard PayPal buttons from the Toolbox (Add to Cart and View Cart). But instead of redirecting the users to the PayPal website, MiniCart will keep the users on your website until they checkout.
