I've totally opted out of daily expeditures like starbucks, and also eat my main meal for a discount or free at work. I'm saving like $70 a week. Add in not buying fast food, spending less than $5 a month on makeup, rarely buying clothes (amazing how long you can keep the same clothes when you aren't constantly gaining weight), it's probably hundreds a month I'm saving.  I opt out of insurance because I'm healthy and don't need meds, so there's a few hundred more a month.  I would really love to see a side by side comparison of a ham's monthly expeditures and a human's monthly expeditures.
