Pls help me buy Switch games

Hi. I'm going to be completely honest. I need a small sum of cash to get switch games. I have a switch but I only have one game which I play a lot and many of you know how that feels. I would really love to get the best games on switch namely Super Mario Odyssey and Breath of the wild. All I need is actually 100-120. The campaign says 251 as telhe minimum is 250. The rest of the money would go to a charity of my choice. Any amount would be very helpful. Thanks :)
