If you have access to the customer use computers at the store, and you find something you think might be a penny, go to the computer and look up the SKU.
If it returns no results yet you are physically holding the item, it just might be a penny.
For the actual purchase of penny items, it helps to use self checkout when it is busy (i.e. a nice weekend day) Only one cashier to try and keep track of 4 self checkout kiosks greatly improves your chances. Ive even been quick enough to buy a penny item with my credit card (didnt have any change on me!) and the self checkout monitor person standing 2 feet behind me. She even came over after I paid to deactivate the magnet in the package....all the while never knowing how much (little?) I paid for it.
