25% off the normal digital price for Zelda. 33% off Splatoon 2. It's rare to see Nintendo discount its first party titles.
If you bought a Switch and don't have this then now is your chance.
Part of a wider sale going through to the 21st and it seems some games are still being added. (though I think personally nothing else we haven't seen before).
You can only access the eStore through your switch - link provided doesn't give any helpful info but I wasn't sure what else to put.
Checkout https://nintypricer.com/au/on-sale for a online list of all items (thanks zero23)
Note: you might be able to combine this with cheaper eStore cards from Big W an earlier post advising they will have 10% off next week but this looks to expire on the day it starts? (https://www.ozbargain.com.au/node/384450).
