After installing Rollo's Chrome extension, and logging in, you can find Rollo activated in several areas of your Amazon Shipment process: 

1) For Labeling Individual Products (FNSKU), the "Rollo Labels" button will appear next to Amazon's button. 

2) Rollo Chrome extension also provides label conversion for SPD and LTL shipments. 

After selecting your desired shipping method, you will find "Rollo Labels" next to Amazon's regular label buttons. 

Note: If you do not see the "Rollo Labels" buttons, make sure that your extension is installed and then refresh the page.
