We don’t know a whole lot about the Nintendo Switch Online, aside from prices and small details of save data on the cloud, play classic NES games, and online play. Heck, we only know that the service will launch in September 2018. We are less than 40 days till then and Nintendo is certainly keeping this tight lipped.
Regardless of details, you can now pre-order two types of subscriptions on Amazon, both digital codes: 3-months ($7.99 USD) and 12-months membership ($19.99 USD).
