Certain Harris Teeters around Charlotte are offering gift card promotions that get you $50 worth of gas for $40. That’s 20 percent off.

The thing is, the Teeter makes you play their game, with their rules, and it’s not as simple as it sounds. The promotions are only offered at certain Teeters and there’s a points system to figure out.

How does it work?

Every time you spend $50 you get 10 points on your account. The bottom of your receipt will say that you accumulated these points with your purchase.

In order to qualify for the gas card promotion you have to have 10 points. But you aren’t trading your points for the gas card. The points are just a pre-requisite for the promotion.

Once you have 10 points, you are able to buy a gas card — and instead of $50 it costs $40. But then you lose those 10 points.

These locations offer the promotion:

Stonecrest- 7852 Rea Road

Steele Croft- 13000 South Tryon Street

Ballantyne Commons- 15007 John J. Delaney Drive

Arboretum- 3333 Pineville-Matthews Road

Hunter’s Crossing- 16045 Johnston Road

The Shoppes at Ardrey Kell- 16625 Lancaster Highway

Providence Commons- 10616 Providence Road

Mountain Island Marketplace- 3540 Mt Holly-Huntersville Road

But some Harris Teeters will honor the promotion, even though they don’t technically offer it themselves.

Quail Corners (8538 Park Rd) will honor the promotion and take $10 off your gas card if you ask them at the register.

Myers Park Shopping Center (1015 Providence Rd) will honor the promotion and take $10 off your gas card if you bring your receipt of over $50 to Customer Service.

While the other Teeters offer the promotion with Exxon, Mobile, and Shell, the Blakeney Harris Teeter (9720 Rea Rd) only offers the promotion with BP.

The Teeter says that this promotion is still in at “test” status, so it’s possible that in the future all locations will get to participate.

Back to the points. So if I spend $100 dollars, I get 20 points? No.

You can only earn 10 points per purchase. If you want to get all of the points possible, you have to ask the cashier to ring up your order in separate purchases of $50.

Sometimes, your points reset.

This happens about every two months. The last reset was in late May, and it erased all of the points accumulated beforehand.

When this happens, try calling customer service, they should put the points that you lost back on your card.

The next reset period is on August 2, and the points can be redeemed until August 16th — after that you technically have to start all over again.

The promotion is running indefinitely.

After August 16, there will be a one- or two-week break from the promotion, before it should begin again.

Thank you Harris Teeter. Yes, I am excited to get 20% off my gas, but I wish you didn’t make it so gosh darn complicated to do so.
