Ahead of Prime Day's start tomorrow, Amazon has been surprising us with plenty of early deals. In particular, today, the retailer has dropped a special treat for Switch owners before the sale begins.Those looking for some new games to keep them busy on their favorite handheld console this summer are in luck. A select number of physical Switch games - including The Legend of Zelda: Tears of the Kingdom on Switch 2 - have had $20 slashed off their price tags at Amazon before Prime Day. What's even better is you actually don't have to be a Prime member to save on them, either.While Tears of the Kingdom is our standout pick from this selection (especially since both Switch 1 and Switch 2 copies are on sale), there are a few more worthy options to shout out. For Pikmin 4, Luigi's Mansion 3, and Mario Vs. Donkey Kong, these deal prices mark their lowest price points at Amazon. So, if you've had them on your wishlist, now is the time to add them to your shopping cart.And while it's not at its lowest price at Amazon, Super Mario Odyssey is definitely still worth having for your Switch. We consider it one of the best Super Mario games of all time, so it's a hard one to go wrong on. Donkey Kong Country Returns HD is another you're sure to have a blast with, as IGN's Logan Plant said this HD Switch version is "easily the best way to play one of the greatest 2D platformers Nintendo has released this century" in his review.There's a lot more still to come from Amazon with Prime Day kicking off tomorrow, too. This year's sale runs for four days, until June 26, so you'll have plenty of time to shop and scoop up the deals that catch your eye. We'll be looking out for even more exciting game deals as they drop over the sale event as well.Hannah Hoolihan is a freelancer who writes with the guides and commerce teams here at IGN.
