That makes sense. But it's also how I spent $6300 one year at the store, where I buy groceries, wiper blades, socks, paper towel, etc.after work I pick up groceries
When I looked at that number, I challenged myself to spend $5200 for a year, ie, average $100/week. That year I spent about $4700, well under my target.
That made me realize that I was spending a lot of extra money when I "stopped at the store on the way home from work."
