No Spend Days

A little over a year ago, I joined a thread over on the Women in Red board where we track whether or not we spend any money each day, and if we do spend money, is it a controlled spend or not.
For me, controlled spend days means I was planning on spending money that day. I may not know the exact amount we will spend, like on grovery shopping days, but I know we’ll be spending.
Today was a no spend day for us. It may sound silly, but I get a great sense of satisfaction on days when we manage not to spend any money at all.
