How to Notice When the Groceries You Buy Get More Expensive
Prices rarely jump all at once. They creep, a few cents at a time, on the things you buy every week. Here’s how to catch it.

Small increases add up
A few cents more on milk, eggs and bread is easy to miss at the register. But the items you buy every week are exactly where small increases matter most, because you pay them fifty times a year.
Watch your regulars, not everything
You don’t need to track every price. Pick the ten or so items you buy most often. Those make up a big share of your bill, and they’re the ones where switching store or brand pays off.
Use your receipts as the record
Every receipt is a dated record of what you paid. Keep them and compare the same item over time, at the same store and in the same size. Here’s an easy weekly routine.
What to do when a price goes up
- Check whether another store you visit sells it for less.
- Try the store brand.
- Compare a different size by unit price.
How AisleSplit tracks it
Every receipt you scan in AisleSplit adds to a price history for each item. When you save a receipt, items that cost more or less than last time show the change, and the Prices page shows the history at every store. More about the grocery price tracker.
