What is the craziest thing you did to save money, big or small amount?

Most profound thing I did to save money: Switched from having a phone number to an all-Discord diet.

Most out-of-my-mind thing I did to save money: Many things probably count, but one I was talking about not long ago was how little I eat. I remember at school, even though lunches weren't free, people were so pressured to eat at lunch time that, when I was seen not eating, I would be provided for because it hurt them more to see someone not eat. Over time it stuck.
