I love cash only living!
I have a routine that I enjoy. My hubby is paid twice per month. We use part of his paycheck to live off of. After I drop him off at work, I make a trip by our local bank and withdraw $120 for each week. We're currently living on a budget of $60 for food and $60 for gas. It was $100 until we moved a little further away from work. We just added the extra $20 so we had a little buffer for additional gas.
For some reason, I just love getting the cash in my hand and sectioning it off in my wallet. After that I typically go fill up our gas tank for the week. I find comfort in this routine. I like paying cash and knowing my boundaries. When it's gone, it's gone.
