Practical notes on grocery receipts, the prices on them, and what a household buys over time.
The official food-at-home figure is an average household’s basket. Yours is different. How to measure price changes on the things you actually buy, from old receipts, without fooling yourself with sizes, sales and swaps.
The most common grocery overcharge is a sale tag that doesn’t ring up, and the receipt can’t show you the tag. What to check at the shelf, four checks the receipt can do on its own, and what to do when the register charged more.
Grocery receipts cut product names to fit a narrow column. How the abbreviations are built, the fastest ways to identify a line you don’t recognize, and why the letter at the end isn’t part of the name.
A sale tag tells you the discount against the store’s regular price. A price book tells you whether it’s below what you usually pay. How to build one from receipts you already have, and the pattern only a price book shows.
Where an old grocery purchase can still be found: the store’s app, your email, a card statement, your photos. What each one keeps, for how long, and why a bank statement won’t tell you what you bought.
The small unit price on a shelf tag is the right comparison more often than not, but not always. When it compares, when it quietly doesn’t, and the third price most people never check: what you paid per unit last time.
A bigger grocery bill isn’t always higher prices. How to split the difference between two months into price changes, buying more, new items, swapped brands and extra trips, using the receipts from both.
