$70-$90...
I try to buy whatever I can at Walmart to save $$$: oats, eggs (1.5 dozen for $1.88!!!!!), frozen chicken (sometimes), brown rice, water, milk, whole wheat bread, frozen veggies, part-skim mozzarella sticks, etc.
Fresh fruits/veggies, greek yogurt and meat are the only things I usually buy at the grocery store these days. Makes a BIG difference!
