If you do not see the Easy Upsell script installed on your site, it's likely because your BigCommerce store is using an old or customized store or cart template, or is otherwise preventing our app from installing our scripts automatically.
Stores like this must do a manual installation of their Easy Upsell script for this app to work properly.
The easiest way to do this is contact us @ support@easyupsell.com and we will designate a manual install from our admin account.
Once we do, a red notification bar will appear on top of your dashboard that will guide you through the quick and easy manual installation process.
