Check the total quantity even when the product looks familiar
A familiar product such as milk or pasta can have a different price meaning when the package size or multipack count changes. Add “Labeled quantity per pack × number of packs bought” to a recognizable product name. If both the outer package total and the amount in each inner bag appear, state which you used.
For a shelf-label photo, check which product size the label describes. A partly matching name does not connect it to the neighboring product. If the package text is unreadable, leave the quantity unconfirmed. The amount remaining after eating is not the total quantity in the package when you bought it.
Leave a record you can trace back to one product
Check the purchased product’s name, variant, labeled quantity, and actual number of packs bought.
For a shelf-label photo, add the store, observation date, and offer conditions as far as you know them.
Match the item’s receipt amount and quantity to the product, keeping the shelf offer separate from the actual payment.
When comparing, align the units and scope of the amount, and leave unconfirmed discounts in a separate note.
Give the shelf figure and receipt figure separate lines
If a shelf price requires buying two or having a membership, record that condition. Seeing an offer is different from actually buying under its terms. After checkout, compare the receipt’s item line and discount details with the package photo.
A fictional editorial example is “Product A, one 500 g bag × 2 / shelf label: two bags for $6 / receipt: $6 for those two bags.” The comparison covers 1,000 g in total and the amount for both bags. These invented amounts illustrate the note format; they are not current prices or a live offer.
Compare matching units and matching payment scopes
If you compare products in the same category by price per 100 g, use the confirmed total weight and the amount corresponding to that quantity. In the fictional example, $6 for 1,000 g equals $0.60 per 100 g. Pairing a one-bag price with two bags’ weight, or one bag’s quantity with the multipack price, produces a different figure.
Grams and milliliters describe different quantities. Do not convert between them without a basis and place them in the same comparison. Different contents or variants also remain different choices even after a numerical conversion. Preserve the products and comparison basis in the note, and check arithmetic yourself in a separate calculation tool when needed.
Leave an unknown share of a basket discount unknown
A receipt may show only an overall coupon at the end, without each item’s share. Record “Item-line amount” separately from “Overall coupon present; item allocation unconfirmed.” Subtracting every discount from one product does not establish its actual unit price.
One observed store price does not establish the price on another day or a nationwide trend. When you buy again, add the new date, product size, and offer conditions. If the price seems different, first read the quantity, pack count, and applicable conditions. Leave the cause unresolved if you do not know it.
Connect the package and receipt within one entry
In Pogaem, collect the package photo and the relevant receipt portion in one entry, using the product name in the title and notes. Leave a connection you recognize, such as “Package A matches the Product A receipt line.” If payment and later photo-organizing dates differ, explain that in the text.
Before sharing, inspect the receipt for unnecessary card details, membership numbers, or other purchases. A photo diary does not automatically read item amounts or determine the lowest price. Use it to revisit confirmed purchase records while shopping later, and retain original evidence separately when you need it.
Frequently asked questions
For a buy-one-get-one offer, can I record just one unit’s price and size?
Match the quantity you actually received with the payment amount for that group. Check both the receipt and actual packages rather than assuming the shelf promotion was applied.
Can I divide an overall coupon equally between the items bought?
You can make a separate personal calculation, but distinguish it from confirmed item-level payments. If the actual allocation is unknown, leave it unconfirmed instead of presenting your split as the product’s established price.
Does a higher price than last month mean the same product went up?
First check that the variant, package quantity, pack count, and promotion conditions match. Two records from one store do not establish a general inflation trend or a manufacturer’s price change.
