if you have amazon prime, you can get 15% cash back on digital cards for the nintendo eShop. The deal expires July 5th, but you need an Amazon Prime card to claim the deal.

I bought the $99 donkey kong card. I should expect about $15 to be added to my prime account.

anyways, I also bought a new microSDXC. 512GB. I think my current one is like 128GB and I want to install Xenoblade 2, which is about 13GB. (Not enough space on my current card.)
