Splatoon 2. Going for $20 less than the typical price. Couldn't pass it up.
It's still going for that price on Amazon USA for anyone interested, btw.
Velocity 2X on Switch. Tried it out on Vita, but saw it going for $5 on Switch right now, so I couldn't pass up a good deal like that. And I get to support the devs for making such a great game as well.
Just picked up a physical copy of the gold cover art version of Wind Waker HD off eBay in mint condition for a great price. I got the digital version a few years back on sale on the eShop, but wanted to get a physical copy for collector's value. :)
