My first instinct would be to categorize the items — produce, meat, dairy, paper goods, snacks, etc-and then show the breakdown by category. If these receipts are true weekly trips (or like the one person who sent in all the receipts per week), some type of distribution of weekly spend?

ETA: price per banana would be more illuminating than total spent and number purchased. (Obviously we can do this ourselves, but lazy girl over here)
