Nobody’s mentioend laundry detergent sheets yet? Super cheap. I buy the Poesie brand. 160 sheets in a box for $9.49. That’s just under 6¢ per load. For my two loads of laundry per week, a box lasts me a year and a half.

Bonus: the box takes up almost no space, 6" x 5" x 3".

Also, white vinegar is an awesome replacement for fabric softener!

“Detergent sheets”, “dryer sheets”, it’s like you’re in a different world with these fantastically strange products! :D

They look like a tissue made of rough fiber, do they dissolve or do you have to throw them away usage?

Another replacement for fabric softener is hair conditioner (diluted with water so it runs better). I only use it when washing polyester fleece, since that gets fiercely static, so it’s nice to be able to use a product we already have at home.
