List is just for myself, and it’s always on paper, written in the rough format of the aisles in supermarkets. Or at least an approximation of the way they used to be as a young adult. I learned the list from Mom, and still do it that way.
From top left down:
Produce & fruit
Baking items (flour, sugar, spices)
Condiments (ketchup, mayo, mustard, peanut butter, jams, sauces)
Pasta and tomato sauce, rice and canned veggies
Then top right down:
Wraps and bags (foil, etc.)
Pet food and stuff (although I now buy that at Petco)
Scooby Snacks (crackers, pretzels, chips, Fritos)
Dairy (butter, milk, eggs, yogurt, cheese)
Meats and fish items go down the middle of the list
So even if coffee beans are WAY over to the back of the store in Wegmans and technically should be listed near Scooby Snacks and Dairy, I still write those items in the bottom third of the left hand column.
