Not only will a bidet save you on toilet paper, but you will actually feel like you have a clean butt after pooping. Initially it feels weird, but after you get used to it, you won’t want to poop without it.
BTW in case you are wondering: yes, you still need toilet paper to wipe the water off. But it is a small amount.
I’m late to this but it’s also the 2nd from the top all time post here so I think it should be said. I disagree, at least with a cheap add-on bidet.
The cheap ones don’t heat the water first so you’re sprayed with cold uncomfortable water, then you’re left with a wet, cold, soggy bottom that you then need to wipe dry, so you still ended up using some tp.
