A worked example
A 1-litre bottle of cooking oil at 62 baht against a 5-litre one at 289 baht is 62.00 versus 57.80 per litre — the big one saves 4.20 a litre. At 5 litres a week that is about 1,092 baht a year.
How to use it
Type the item, the shelf price and how much is in the pack, then give the rows the same unit — litres, kilograms or pieces. The price is divided by the quantity as you type, which is the price per unit. When several rows share a unit, the cheapest one per unit is marked for you. The total underneath is what the whole basket actually costs, so you can check it before you queue up. Everything is worked out on your device; the numbers are never sent anywhere.
- Type the item, its price and how much is in the pack.
- Use the same unit on the rows you want to compare.
- Read the price per unit and the total; the best-value row is marked.

- Will my list disappear if I close the page?
- No. It is stored in this browser. It will be gone if you switch devices or clear your browser data — save it to your notebook if you want it to last.
- Can I compare items with different units?
- It only compares rows whose unit matches. If one is in grams and the other in kilograms, convert them to the same unit first.
- Where does a saved note go?
