How do I explain this, first off I went to sell some switch games, controllers, docks and etc. I have 6 items with me:

Nintendo Switch Case: $20 (At Walmart)
Dock: $20
Third Party Controllers: $30 (On Amazon)
Mud Runner: $55 (At Walmart)
Mario Cart: $80 (At Best Buy)
Controller Holder: $20

And the price I will say is $150 or $175 as used items altogether. And I CAN'T believe how much they often me, $60 for all 6 items. $10 for each item, I was super surprised and left the store.
