Gotta watch that fine print.
Amazon's Twitch Prime streaming subscription service has offered a lot of downloadable loot for games, and now Switch Online time is included.
Members of Twitch Prime, which includes anyone with a subscription to Amazon Prime, can visit twitch.amazon.com/nintendo to claim a three month Switch Online individual membership code. If the membership is maintained for 60 days, a code for nine additional months will unlock.
The three month offer is slated to last until September 24, and the nine month code can be claimed until January 22. If time has already purchased it can be used to extend an individual membership. Family plans are not supported.
