On now and running through next week, the Nintendo Summer Games Sale is live on the eShop. You can find the list of games through the eShop on your Switch console or here: https://www.nintendo.com/deals/

As a matter of fact nearly 80% of the games in my own wishlist saved to my profile are on sale, and I think I'll be pulling the trigger on SteamWorld Quest: Hand of Gilgamech and Thronebreaker: The Witcher Tales, both at 50% off.
Other titles that caught my eye:
Sale ends on June 17th, treat yourself to something nice.
