Go to Account & Coins, click "To-Do History", then either scroll down to look or use ctrl+f & type the name of the game you haven't done the survey/registered yet. It gives you the expiration date. For example, it tells me I have until Oct 24, 2019 to register a code for Bayonetta 2.I'm already almost at platinum. How long is long? I want to be able to hold onto some games until the next club nintendo year starts.
