Nintendo has updated its terms and conditions surrounding pre-orders that are placed through the Nintendo eShop. Thanks to Resetera member Garou, it’s come to light that you will now be able to cancel pre-orders for games up to seven days before the title launches whereas previously there was no option to back out and reverse the transaction. There’s also been changes to the payment process: billing will now take place seven days prior to the launch date of the game, not at the time of the pre-order. Here’s some more info from the official US Nintendo website but you can read the whole updated terms here.
The required funds will automatically be paid out of available funds at the time of payment. The expected payment date is no sooner than seven days before the product is released. (For bundles with different product release dates, payment will be processed no sooner than seven days before the first product release.)
You can check the product’s expected payment date by selecting Shop Menu in your Nintendo Account settings then selecting Your Pre-orders, or via Your Pre‑orders under Account Information on Nintendo eShop on your device.
