The key here is to minimize the number of third-party widgets used on any critical e-commerce pages. Also, it's important to set up any widgets you do use to load asynchronously — i.e., their loading doesn't delay other operations on the web page.
One last thing: Have a baseline. If you decide to make any changes to your widgets, be sure to monitor your web performance before and after the change. Make sure that the monitoring tool you choose can give you real user data (and ideally present the actual browser-specific user experience) for all of your e-commerce pages. The monitoring tool should also be capable of correlating the page rendering process with specific numerical measurements so you're able to quantify the potential impact of any site changes.
