NAPA vs. AutoZone vs. Advance vs. O’Reilly

NAPA Auto Parts, AutoZone, Advance Auto Parts, and O’Reilly Auto Parts are four popular auto parts retailers. While they sell similar products, they have different store policies and services available. We’ve reviewed the following categories to point out the differences and similarities between NAPA, AutoZone, Advance Auto Parts, and O’Reilly: inventory and pricing, service centers, and customer opinions.

Inventory and Pricing

NAPA Auto Parts, AutoZone, Advance Auto Parts, and O’Reilly all have wide inventories online and in stores. They also have comparable pricing and will price match local competitors.

NAPA Auto Parts

NAPA Auto Parts stores are individually owned and operated, so product inventory may vary by location — and parts listed online won’t necessarily be available at your local NAPA Auto Parts. You can, however, search for parts by entering the year, make, and model of your vehicle on its website. You can then order online or contact your nearest NAPA Auto Parts to see if it has the item in stock. For online orders, there is a flat-rate shipping fee of $7.95.

According to our communications with the company, the auto parts retailer does not price match, but, locally, some NAPA Auto Parts stores may price match with local competitors. This policy will vary by location.

Other NAPA savings opportunities include:


You can search for specific parts for your car on AutoZone’s website when you click “Add a Vehicle.” AutoZone offers same day in-store pick-up for parts that are available at your nearest AutoZone. For online shopping, AutoZone offers free shipping on ground orders of at least $25. Some items are even eligible for free next-day delivery.

AutoZone does not price match online pricing, but, a customer service representative said AutoZone will price match any competitor that has a physical store location, as long as you have proof of the competitor’s price.

AutoZone also offers the following ways to save:

Advance Auto Parts

The Advance Auto Parts website allows you to add a vehicle when searching for products online; you’ll need to enter the vehicle type (car/truck or motorcycle), year, make, model, and engine. Store pick-up is available as soon as 30 minutes after you reserve the item online, as long as it is in stock at your local store. Additionally, free shipping is available for orders over $25 to any address in the continental U.S.

Advance Auto Parts does price match as long as the product is identical or highly similar and in-stock from the competitor. Advance Auto Parts stores cannot match online competitors, only brick-and-mortar stores. Additionally, price match items at must be available for same day pick-up from the competitor if they are available for store pick-up. For any price match in-store or online, you must provide proof of the competitor’s current, valid lower price for approval by an Advance Auto Parts team member.

Advance Auto Parts also offers other ways to save:

O’Reilly Auto Parts

O’Reilly Auto Parts allows you to search its inventory online by product, category, brand or part number. You can browse by category, too, and filter the category or search results to fit your vehicle.

O’Reilly does price match in-store purchases with identical items from brick-and-mortar competitors. See more about the O’Reilly Low Price Guarantee and other ways to save in our related article.

Service Centers

In addition to selling auto parts, all four stores can point you to a repair shop, if needed. NAPA has its own affiliated service shops; O’Reilly Auto Parts, Advance Auto Parts, and AutoZone refer customers to local mechanics and provide basic in-store services such as bulb replacement.

NAPA Auto Parts

NAPA Auto Care Centers are full-service repair shops. The advantage of using a NAPA Auto Care Center is that it offers a free Peace of Mind Nationwide Warranty.

To find your nearest NAPA Auto Care Center, use the shop locator.


AutoZone does not have its own repair shops. It will do things like replace brake lights (most of the time) and install batteries but AutoZone will not change your oil. It does, however, refer customers to local mechanics in its Shop Referral Program. Individual repair shops will have their own warranty and protection policies, an AutoZone customer service representative said. To find a referred repair shop near you, use AutoZone’s Find a Repair Shop locator.

Advance Auto Parts

Advance Auto Parts does not operate repair shops, but does offer a mechanic locator on its website. You can enter your vehicle make and filter to the exact service you need to find a local mechanic that can service your vehicle.

Advance Auto Parts also offers in-store services, including battery testing, battery installation, check engine light scanning, loaner tools, starter and alternator testing, oil and battery recycling, and wiper blade installation.
