NAPA Promo Codes in September 2026

The easiest way to get free shipping is to spend $49 or more in a single order. That unlocks free one-day shipping, so it pays to group your parts into one order instead of placing several small ones.

If your cart is sitting just under $49, it often pays to add one more small item to cross the line. A $10 part can end up cheaper than what you'd spend on shipping.

Keep in mind that not everything counts toward the $49. Core charges, taxes, special-order items, and hazmat products like AGM and lithium batteries are left out of the total. They get two-day shipping instead of next-day, and orders to Alaska and Hawaii still pay for shipping. If your order doesn't qualify, your shipping cost is calculated at checkout based on what you ordered and where it's headed.

Buying online and picking up in store is another simple way to skip shipping fees. NAPA emails you when your order is ready, usually within two hours of placing it online. Just bring a valid government-issued photo ID and your order number to pick it up. This option is available at participating stores only.

Yes. Military members get a discount of 5% to 20%, and it's open to more people than you might expect. The offer covers every branch of the armed forces, including active duty, veterans, retirees, and reserves, plus their families.

To claim it, reach out with an active military email address or send a copy of your DD Form 214 along with your contact info. Once you're verified, you'll unlock this exclusive saving. Active-duty members get an extra perk too, since NAPA ships every order to your door for free. That means new parts can be waiting for you by the time you get back.

Discounts at regular NAPA stores work a little differently. Many locations are independently owned, so military and first-responder offers can vary from one shop to the next. Since the discount isn't guaranteed, ask your local store whether they offer one before you buy, and bring a valid ID when you do.

Sign up for NAPA emails before you place your first order and you'll score 20% off. It's a one-time welcome code, so the trick is to subscribe first and then shop, not the other way around.

To score it, head to napaonline.com. A pop-up will appear inviting you to sign up for the email newsletter. Enter your email there and the discount lands in your inbox, ready to use on your first order only.

Keep in mind that NAPA lets you use just one discount per order. Since you can't stack codes, the smart move is to line up your welcome discount with a cart of $49 or more. That way you get 20% off and clear the free-shipping threshold in the same order.

Yes, and it's one of the easiest ways to save if you're already a member. The NAPA AAA discount gets you 10% off the retail price on thousands of auto parts at participating NAPA Auto Parts stores.

Claiming it takes just a second, and how you do it depends on where you shop. Picking parts up in store? Show your AAA card at checkout. Ordering online for ship-to-home or in-store pickup? Just enter your AAA member info at checkout. If you go the pickup route, bring your membership card along when you pick up your order.

Here's a detail worth remembering. AAA is the only outside parts discount program NAPA accepts, which makes your membership a genuinely useful card to keep in your wallet whenever you're buying parts.
