This bundle is less about a deep discount, and more about getting a bunch of extras thrown in. For $30 over the usual price of a Switch, you get:
1. A Switch console in your choice of colors.
2. Your choice of one of five games: Mario Kart 8 Deluxe, Legend of Zelda: Breath of the Wild, Super Mario Odyssey, Splatoon 2 or Super Mario Party (each of these usually costs $50 to $60).
3. Your choice of a free accessory: A portable power bank, a carrying case/screen protector combo or a camo messenger bag.
Just remember that the aforementioned Switch Lite is coming in two months for $200, if you'd prefer to wait. And this $300 Switch is also getting an update with better battery life in September, so you might want to hold off until then.
