It's awesome to be able to buy Nintendo gift cards directly from amazon without having to go to a store to pick one up for use with the Nintendo e-shop. I like to keep my credit card information limited to as few outlets as possible, and this way I can purchase digital games off the e-shop without putting in my information. The whole process is extremely quick, with only a few seconds from the time I purchased the digital card to the email notification letting me know my claim code was available. After that, it's a cinch to purchase games for my Switch either online or from the system itself. This is a great way to go about it if you are concerned about safety!
