Just to clarify, there are still things I will be buying, like food. Food is a necessity. But I will stop buying random food when I have food at home that I could eat. That's one way I'm going to save money.
I'll still have to buy presents for Mother's Day and Father's Day, but I'm going to try and make gifts this year. For Mother's Day, I'm writing down memories of my mom, things she's taught me, and questions I have for her, which I'm going to put in a jar so she can open them up one at a time. It doesn't cost me anything, but better than that, it's a more meaningful gift than flowers.
I will keep buying things like shampoo and conditioner and deodorant, because while they might not be absolutely necessary, I need them in order to go to work, or hang out with my friends. But I am going to stop buying hair stuff just because I want it.
So that's what I can buy.
