Find out which store is actually cheapest on the things you buy.

Not which store advertises the lowest prices — which store wins on your items, with a dollar figure on how much switching would save. Per year. Drawn from your own logged prices, not aggregated panels or flyer scrapes.

How it works

For every item you've logged at two or more stores, PricePrint computes each store's average unit price for that item, then declares the cheapest store the winner. The store with the most wins across your whole catalog is the overall cheapest store for you.

The annual savings estimate is the sum of (overall average − cheapest store price) × your typical purchase size × purchases per year, capped per item so a single outlier can't blow the headline number into fantasy territory. It tells you what switching to the cheapest store would save you — assuming you keep buying the same things at the same frequency.

FAQ

How many items do I need before this works?: An item needs prices logged at two or more stores to count. The headline numbers stabilize around 25–30 items spanning multiple stores. Below that, single outliers dominate.
Why is my "cheapest store" different from what the news says?: National rankings average across millions of shoppers buying different baskets. PricePrint averages across your basket — which is almost certainly not the national average basket.
Does it factor in how often I buy each item?: Yes. The savings number is purchase-frequency-weighted — items you buy weekly contribute more to the total than items you buy twice a year.
Does it know about gas, parking, or driving time to a farther store?: No. The savings number is just the grocery delta. If the cheapest store is 30 minutes farther, you have to weigh that yourself.
