We wont charge you for channels you aren't using. You are billed at the end of every month for the channels you have had open, prorated for the amount of time the channel was open for. For details on membership fees, see our pricing page.
Uninstalling the app or module will not immediately close down your Shopping Feed account. You must delete channels from the channels setting tab to stop being charged for the channel. To get help closing down your account, please contact support
