Our Cash Back Button extension is designed to pop up and remind our Members of the Cash Back offer available when they visit a partnering merchant's website. There currently isn't any way to directly update the settings for the extension to only pop up the notification for one merchant. You can go into the settings for the extension and add websites where you don't want the Cash Back Button notification to appear to the "Hide activation reminders on these sites" list. You can also uninstall the extension and shop directly through our website, Rakuten.com, or through our mobile app on Android phones, iPhones, and iPads.
