The NYC grocery field guide
Different packs.
Same measuring stick.
The price on the front of a shelf label tells you what a package costs. The unit price helps you compare different package sizes. Start by making sure the products belong in the same comparison.
Compare grocery pricesFree comparison starts with grocery staples.
Build your shopping list on the map, then compare.
Copy the label.
Keep the differences.
- Rice
- Same variety; net weight and package price
- Milk
- Same kind; volume and package price
- Eggs
- Same size; count and package price
- Offer
- Card, coupon or quantity requirement
Bring the package details into the comparison.This is a worksheet for reading labels, with space for the actual information you find.
Match the food, the unit and the conditions before choosing the pack.
First decide what counts as a substitute.
Write down the item you intended to buy. Decide which differences you accept before browsing the shelf: another brand, another package size or another variety. Keep a requirement fixed if changing it would mean buying something you do not want.
Put dry rice beside dry rice of a suitable variety. Give ready-to-eat rice its own comparison if that is a different purchase for you. A smaller label number does not settle whether the product meets your list. For a whole-trip method, use the shopping-list guide.
Put both prices over the same unit.
Look for the words after the unit price, such as per pound, per ounce or per item. The NIST Unit Pricing Guide recommends consistent units within a product category so different brands and sizes can be compared.
| Item | Copy from the label | Keep beside the result |
|---|---|---|
| Rice | Price and net weight | Variety and dry form |
| Milk | Price and fluid volume | Kind of milk |
| Eggs | Price and count | Size and required labels |
| Canned food | Price and labeled quantity | Product and pack format |
If the units differ, convert the quantities into a shared unit before dividing package price by quantity. Use a calculator rather than comparing the printed numbers alone. Keep weight and fluid volume separate; an ounce and a fluid ounce measure different things.
Write the package price and quantity beside your calculation. That makes it easier to spot a copied size or misplaced decimal before choosing.
Use the price you can actually get.
A shelf can show a regular price, a member price and a separate offer. Copy the condition beside whichever price you use. If a coupon needs clipping, check that step. If an offer needs several packages, calculate using the purchase you would actually make.
- EligibilityCan you meet the card or coupon requirement?
- QuantityAre you comparing the required purchase, including every pack?
- MatchDoes the offer apply to this size and variety?
- Unclear labelAsk the store before treating the offer as usable.
Keep a conditional price separate from an ordinary price until you have checked the terms. The multi-buy guide walks through that decision.
Choose the package for this trip.
Now look at the package total alongside the unit comparison. Decide what fits the amount you need, the cash available for this shop and the space you have. You can choose a smaller pack even after comparing units.
New York State's Money Savings Guide recommends list planning, circular checks and unit-price comparisons. Use those checks together: the item still has to earn its place on your list.
Find a matching offer.
Then check the label.
Search for the groceries on your list on the map. Add any results you want to your shopping list, then open the free comparison. With an empty list, the comparison starts with grocery staples.
Open an offer's details and keep its size and terms beside your notes. Confirm missing unit information at the store before deciding between packages.
Your usuals.

Is the lowest package total the best value?
It depends on the amount inside and what you will use. Compare matching units, then decide whether the package fits this trip.
What if the shelf label uses a different unit?
Copy both quantities and convert them into the same unit. If the label is unclear, ask for help rather than guessing.
