How much do you spend a week on groceries? What do you think about $100.00 a week to feed a family of 4; including 3 packed lunches a day?

I'm curious what you spend a week, give me your feedback! The pictures are one weeks worth of groceries, I spent a total of $90.87. Before I go to the store, I check to see what I have. I don't have to buy potatoes, carrots, pasta every week, or toothpaste, shampoo, toilet paper, paper towels, or napkins. When I get to the store, I check to see what types of meats are on special, and I try to plan my meals around that. I pack three lunches a day, once in awhile my boys ask to buy lunch, most times they do not like what the schools serve. I make three stops, all close to each other and my house. Giant Eagle $51.24, Marc's $25.18, and Beiler's $14.45. I have $9.13 left to get more milk later in the week, and let the boys buy lunch one time each. What did I buy.........

Dairy-1 gal skim milk, 1/2 gal whole milk, coffee creamer, pint half and half, 2 packages shredded cheddar, 1 package american cheese, 1 package string cheese, 18 pack eggs
