Lmao , love how you posted my thread on ERA for the same question.
Thanks! Yeah it doesnt show any expiration - I just wanna finish my run of Super Mario Odyssey before I redeem the code so I can take advantage of the NSO NES and SNES games.
Jejejeje, it was one of the first links that came out related to the NSO expiration xD
BTW, congrats on your Switch purchase with 20 games to boot!! Which did you get?
