Yeah, it's amazing how much laundry you can get done at a tiny fraction of the cost. And after making my own soap, I've even stopped using my dishwasher and just dissolving grated soap in water and hand washing everything.
After trying a couple laundry mixes, I'm just down to a half cup each of washing soda and oxygen bleach per load and it works great. Borax if I'm washing my shower curtain for the mold.
