Sign up here for Harris Teeter's e-VIC program. Every week they have an item that is automatically discounted when you use your card to purchase it. This week they have $3.00 off a 24 pack of Harris Teeter brand water. The regular price is $4.97, so if you buy it with your card, you will automatically only be charged $1.97. A lot of times these e-VIC specials cause an item to be almost free, so it is definitely to your benefit to sign up.
On top of that, your name will be entered into a drawing every week to win $100 or more! Just be sure to check your email every week to see if you've won and to see what the e-VIC special is for that week.
