Arm & Hammer Advance White trial size for 1 cent at CVS (one per transaction)

Heads up! Check your CVS for the Arm & Hammer Advance White trial size (0.9 oz) for just a penny. The sign at my CVS said it was limit 1 per transaction, leading me to think I could grab another cheap tube of toothpaste the next time I'm in the store. Trial sizes are great for traveling or storing in your desk at work.
