You found an item you think might be a penny. You walk it to self-checkout. Now comes the part where a lot of beginners slip up: scanning the wrong barcode.
The tag barcode isn’t the product barcode
The barcode printed on a yellow clearance tag is a shelf-tag barcode. It isn’t the product’s UPC. According to PennyCentral, scanning the yellow tag at self-checkout triggers an associate alert every time. That alert exists to stop label-swap theft, but the result for you is the same: an employee comes over, and your possible penny find gets noticed.
So the rule is simple. Never scan the yellow tag. Scan the barcode printed on the package.
When a box has more than one barcode
Many boxes carry several codes. Only one is the UPC. To find the right one, compare the digits under each barcode with the UPC listed for that item in the Home Depot app. The one that matches is the one to scan.
Cover the QR code
Some boxes have a QR code close to the UPC. If the scanner reads the QR code instead, the register can pop up an associate-assist message. PennyCentral’s fix is mechanical: hold the box with your thumb over the QR code so the scanner only sees the UPC.
How the test scan works
- Take one item to self-checkout.
- Scan the barcode on the package.
- If it rings up at $0.01, it’s a penny. Buy that one, finish the sale, then quietly go back for the rest if there are more.
- If it rings up at any other price, remove it and tell the attendant you were checking the price.
That’s it. Nothing is committed until you pay.
One item or all of them?
If there are several units on the shelf, you have a choice. Testing one first is less awkward if it turns out not to be a penny. But a penny sale can alert staff, and some stores act fast to pull the rest. Taking them all at once secures the whole find, but it’s more awkward if the scan fails. Neither is always right. It depends on how many there are, how valuable they are and how busy the store is.
Same product, different barcode
Two boxes can look identical but carry different UPCs, for example an older version and a newer replacement, or chrome and brushed nickel finishes. The old one might be a penny while the new one rings up full price. If you’re buying several, check that every box has the same UPC.
Why the scan matters most
Tags, app messages and empty shelves help you decide what to test. The scan is the only thing that tells you the actual price. Learn the other clues in our guide to reading clearance tags, and see what to do when the register refuses an item entirely in penny items vs stop-sales.
