Nintendo Switch Game Vouchers - Everything You Need To Know
6. You Don't Have To Spend Both At The Same Time
A misconception I saw was that you must spend both vouchers at the same time. This is incorrect. They can be used independently. You could spend one voucher upon purchasing them, and the other sometime before its expiration date.
There's a reason why this is so important. Nintendo's website states that the "selection of eligible software will continue to grow over time." This indicates that the list of eligible games will change sometime between now and July 31st. It'd be best to wait a month or two before spending both of them. Especially because E3 occurs in June.
There's no doubt that whatever Nintendo reveals at their E3 Direct will find its way onto the Eligible Game List.
