During the recent Super Mario Maker 2 Direct, Nintendo unveiled a special promotion that can be utilized with the game and others.
If you are subscribed to the Nintendo Online Membership, you can purchase a Nintendo Game Switch Voucher for $99.99. These grant you two vouchers that can be redeemed for eligible games that can be purchased via the eShop. The vouchers must be used within a year from purchase, but do not have to be used at the same time.
Most of the titles shown off during the segment of the direct usually retail for around $50 – $60. The example given included Super Mario Maker 2 and Super Smash Bros. Ultimate, both $59.99 titles, totaling to $119.98. This gives a saving of $19.99.
