My list was fairly short but I was getting some bulky items including milk and cereal. I did my shopping and went through the self checkout so I could bag my own groceries in an attempt to get everything to fit without having to repack once I got to my bike. Milk and the cereal box turned out to be a tight fit. I had to strap the cereal on top of my rack otherwise I got both bags inside the panniers.
Here's the packed bike after getting home.
Here's the spread: milk, Lucky Charms, Eggo waffles, box of mini donuts, 5 chocolate milk boxes, apples, and Clementine oranges.
