Dunno if this is a new eShop sale or just the one Zero mentioned above (edit: er, last page), but I was looking through the games on sale right now and WOW there are some deals. I have no money to spend on such things right now, but if I did I would snatch up deBlob for $15 immediately.
Of course, it excludes almost all Nintendo titles and there's more stuff for PS4 and XBONE if you have those, but there are a few Switch games which may be worthwhile. The two Nintendo titles I see are Splatoon 2 and Donkey Kong Country Tropical Freeze. Some of the ones I think are notable are Mega Man 11, Crash Trilogy, Dragon Quest Builders, Sega Genesis Classics, Puyo Puyo Tetris, Sonic Mania Plus, and Tales of Vesperia.
