In order to not bog down the usual Deals discussion, we’ll move over more detailed discussion over here.
No current sales
The South American eShops are unique in that purchases are made through a web store, and codes are sent to the user’s email.
These codes also happen to be redeemable in accounts from other regions (we have confirmed at least the US), and also award the account the respective Gold Coins for that title. Accounts for these regions do not make use of the coin system, therefore select recent titles might not award them. Take this into account when purchasing titles released after September 20, 2019.
Hong Kong: https://store.ninten...-released-games
Codes for territories like Hong Kong above are likely not compatible with American and European accounts.
The sites accept payment through Visa, MasterCard and American Express cards (no Paypal support at this point in time, but HK supports Alipay), and will charge your card in their local currency, so be mindful of your card’s foreign currency policies. It is also highly recommended that you refrain from using a debit card for this, just in case.

The details (for Argentina, but mostly the same in the others)
I would recommend you to set up a new Nintendo account. Since at no point you actually need to log into an Argentinian account on your Switch, you can just have a secondary account for the sole purpose of using the web store, without going through the trouble of swapping regions on your existing account. Since this would be a regular Nintendo account, you can set up two-factor authentication on it and everything. Make sure to use an email address you can easily access.
Once signed up, you can log into the web store and put your selected items into the shopping cart. Please note that Nintendo Online subscription codes are not compatible with your foreign account. On a similar note, at this point in time, I haven’t tried (or seen an attempt) to redeem DLC to a foreign account, so please keep that in mind.
To proceed with checkout, you’ll need to enter a National ID Number (a random number will do, but you can google a picture of the document for reference) and a billing address. There have been reports of successful purchases using one’s regular address (with slight alterations to fit the requirements of the form) or a local or made-up address. This very much depends on your bank and other personal circumstances, and sheer luck. For some it has worked right away, and others have been denied only to have it work a couple of weeks later with the same info for no reason. Does the site check your info against anything? Dunno.
Afterwards, the site will request your credit card information, and you get your result. If successful, be on the lookout for a “Confirmacion de compra digital de Nintendo” email that will include your codes. In times of high demand, the messages could take anywhere from 30 minutes to 48 hours to arrive, but usually you should get it within 15 minutes.
