When I was a child, my mom collected shoeboxes. Big boxes, tall boxes, small boxes, etc. Their varying sizes made them a great storage option.
My parents own a slew of vending machines in and around my hometown and keeping track of their expenses during the year was never a huge priority. As a result, my mom finds the best-priced soda at one store then travels to the next, even if it’s only because she has a coupon for potato chips. She had receipts from Sam’s Club (a retail warehouse), gas stations, grocery stores, and more. It’s a lot of driving and even more receipts.
