Update: It will depend on availability in your area, but you can get a Switch for just $225 from Google Shopping Express via Target with promo code EXTRA25.
The Nintendo Switch basically never goes on sale, but if you still haven’t picked one up, it’s down to $280 on eBay today, with no sales tax for most buyers. It’s only a $20 discount, but hey, that’s enough money to buy Stardew Valley.
