App or In-Store Scanner?
Use the in-store price scanner, not the app — because the app frequently cannot see the items you are hunting at all. A penny item is discontinued, and discontinued products often drop out of a retailer's consumer app while still sitting on the shelf. That means "Product Not Found" is not evidence the item is worthless; it is often the app confirming the item has been discontinued, which is the first condition for a penny. The in-store scanner reads the same register system that will charge you, and the register itself is the final word.
Why does the app say "Product Not Found"?
Because the product has usually been removed from the consumer catalog. An app is a shopping surface — it lists what the retailer wants to sell you. A discontinued item is precisely what it stops listing.
So the message is close to the opposite of what people assume. It is weak evidence that the item is discontinued, which is the precondition for a penny price — not evidence that it will not scan.
What is the in-store scanner actually reading?
The store's own price file — the same system the register uses. That is why it can show $0.01 for an item whose shelf tag still says $1.25, and why it is the tool worth walking across the store for.
It is not infallible. Scanners can be out of service or slow to sync, which is why the register remains the final word.
So what should I actually do?
Use the app before you go, for what it is good at: browsing, item numbers, and confirming a product exists. Use the in-store scanner in the aisle for price. Treat the register as the answer.
If the scanner and the tag disagree, the scanner is closer to right. If the scanner and the register disagree, the register wins.
Does this apply to other chains?
The mechanism is the same anywhere penny pricing exists: the consumer app reflects what is for sale, and the in-store scanner reflects the price file. Dollar General shoppers rely heavily on its app scanner, with the same caveat — a missing item is not a no.
The rule holds wherever penny pricing exists: a missing item in an app is not a no.

FAQ
Does the Dollar Tree app show penny items?
Often not. Discontinued products tend to drop out of the consumer app while still being on the shelf, so the app is the wrong tool for confirming a penny price.
What does "Product Not Found" mean?
Usually that the item has been removed from the consumer catalog — which is the first condition for a penny price, not a reason to put the item back.
Is the in-store price scanner accurate?
It reads the store's own price file, the same system the register uses, so it is far closer to the truth than a shelf tag. The register is still the final word.
Why does the shelf tag show a different price?
Tags are not reprinted when an item is marked down to $0.01. The tag reflects the last printed price, not the current system price.
Should I use the app at all?
Yes — for browsing, item numbers, and checking a product exists before you go. Just do not use it to decide whether something is a penny.
