I have a similar list of staples when I shop there, but I have to always shop somewhere else, too - I am the reverse of most folks - I go 2-3/month when I run out of the staples and shop a regular grocery 1/week.
I buy (when I run out)...
Milk
Eggs
Butter
Olive Oil
Flour
Sugar
Salt
Whole grain white bread
Cheeses of 4-5 types (shredded, sliced, fresh mozza, etc)
Lebanon Bologna (a family member loves this)
Baking Powder/Soda
Pretzel Rods (a family member loves these)
Graham Crackers (another family member loves these)
Marshmallows
Muffin Mix
Canned Pumpkin
Whipped Cream / Half and Half
Tortillas/Taco Shells/Taco Seasoning (or discount name brand packs) - family loves their seasoning mix
Frozen Cheese Ravioli
85% all beef frozen burgers
The produce picks - all that are still there (since they sell out quickly some days) - ALWAYS get these if you're there!
I stay away from all the beverages, paper products/toiletries, meats, frozen (other than the burgers and ravioli), cereals, bakery, etc since I routinely get better deals at my local store every week...
