How much is my stuff worth and where to sell? 😅

Im trying to save up for a gaming pc and I have some Nintendo stuff I can sell but im not sure where to sell and for how much. I have a used Nintendo switch oled in decent condition (around 2-3yrs old) and a switch lite that around 3 (some scratches). I have the switch case and some games (Mario odyssey, Zelda botw, totk, skyward sword, Mario wonder, metroidremastered, Mario 3d world+bowser fury all in decent condition.
