Nintendo of America has added some new rewards to the My Nintendo service to celebrate the launch of WarioWare: Get It Together! A physical button pin set featuring Wario, Young Cricket, 9-Volt, and Mona can now be redeemed for 500 Platinum Points. Shipping costs $7 USD as per usual, but you can always combine multiple rewards or My Nintendo Store items to your order for no extra shipping charge. Three digital rewards (two desktop/mobile wallpapers and a September calendar) are also being offered for 50 Platinum Points each. My Nintendo items are only available while supplies last, so make sure to act fast if you’re interested. WarioWare: Get It Together! is out now for Nintendo Switch.

Physical reward through My Nintendo. Those have been extremely rare since the rebranding.
Exactly and most are either worth it or not, usually the worth it ones sell out so quick.
I still use my 3DS case that I got from Club Nintendo. Sadly never got any cool collectibles from there.
i think the only Club Nintendo rewards I wanted but missed out on were the golden Wii nunchuck, the giant 3DS AR card and that Mario hat for the year end rewards from the first year they had it in the states.
