Question about Nintendo The Legend of Zelda: Tears of the Kingdom Digital Download Code

If I'm not mistaken, only Nintendo has the possibility to change the price because it's identical to the one on their store.

Personal opinion:
Nintendo might prefer to create jobs than to sell at low prices "the retailer would get nothing".

As a result, the advertising side of the business would drop because no one would have any interest in selling their products. "free advertising"

In July 2020, Nintendo issued a new policy so that digital games are sold with a different procedure. That's why(?) download codes have been just as expensive as the games in the eShop ever since. Unfortunately I can't find a decent article about it anymore and even then the news was really sparse... So no guarantee.

Prices are set according to supply and demand, suppliers and availability of goods. For all these reasons, they vary very regularly and vary from one model to another (as with video games that are downloaded and those that are bought with a box).
