I did an experiment a while back to see how much cash I was spending eating at work.
Coffee from Starbucks and a breakfast snack at work = $7 per day
Lunch at work = $5.50 per day
Afternoon juice, Diet Coke (when I was still drinking them), or bottled water from the vending machine at work = $1 a day.
That was 13.50 PER DAY or almost $70 a WEEK!
Holy crap did I ever give myself a nice raise by bringing all of my food and drinks from home!
City - Jack takes her lunch every day for work and it *also* drives her crazy when I wash out Ziploc bags and reuse them so we compromised and I bought a couple of those plastic sandwich-shaped boxes to put her sandwiches in instead of using Ziplocs. We just wash them out and rotate and it has saved about $5 a month on buying new bags
