peanut wonderings: what are some of your staples?

I love to grocery shop. It's addicting. If I had a car, I think I'd go to the store everyday because I love to walk up and down each aisle and dream up delicious dishes. Whenever I am at the grocery store, I  observe people and their carts. Shallow or not, I think you can tell a lot about a person by the cart he/she pushes around.

 [I am too embarrassed to show you a picture of my fridge which is a literal piece of trash. The door is broken. The shelves hold up the condiments with a twisted hanger. I will save you the shock of seeing it and just post this picture of my dream fridge. Image source.]

What are some of the staple items you always grab while at the store? Is there a special treat you hide from your spouse/roommates/kids/dogs? Do tell.

Here's a sample of my normal list:
-apples                                                      
-oranges                                                     
-bananas
-lettuce
-tomatoes
-basil
-thyme
-potatoes
-onions
-carrots
-bell pepper (color depends on price)
-broccoli
-celery
-pizza sauce
-pepperoni
-Kraft mac & cheese
-chicken broth
-black beans
-corn
-tortillas
-diced green chiles
-flour
-sugar
-cheerios/raisin brain/marshmellow mateys
-whole wheat bread
-deli lunch meat
-boneless, skineless chicken breasts
-leanest ground beef
-eggs
-yogurt
-1% and whole milk
-mozarella cheese
-sharp cheddar cheese
-pringles
-pretzels

My weekly food budget is $70 so I don't buy all of these items every week. I almost always go over the budget by $10. It is so aggravating, but I will not give up my fresh fruits and vegetables. What is my special treat? Well, it depends on my mood: a bag of skittles or a milk chocolate Dove bar. I immediately hide them upon my arrival home. Not even Tim knows my hiding place.
