On the top of the pantry, I have some kitchen gadgets such as, an onion chopper, cheese grater, and baskets for bread and chips. The next shelf down I have my tea, sugar for coffee/tea, honey, and coffee. Under that shelf, I have the salty snacks like pretzels, nuts, popcorn, etc. The last shelf, I have canned items like sauce, rice, pasta, soup, baking needs like sugar and flour.
On the floor, I keep my lunch boxes (because I used to be a teacher), coolers, paper towels, and napkins. I also keep my extra containers to hold my snacks.
