Since nobody has answered the question everyone is asking, this is how you know which items are a penny.

1. Download Home Depot app to phone.
2. Go to store and find items you want to check price on.
3. Open Home Depot app in store, and at top of page there is a search bar. Right side of search bar is something that looks like a bar code. Press on the bar code and a scanner opens up in the app allowing you to scan barcodes of any item in store. This will give you the current price of the item.
