O’Reilly Auto Parts Coupons & Promotions FAQ

Save more on the parts, tools, and accessories you need to get the job done right. Explore our frequently asked questions to learn how to use O’Reilly Auto Parts coupons, online promo codes, and limited-time offers. Whether you’re shopping online or visiting our Professional Parts People in-store, we’re dedicated to helping you find the best value for every repair.

How Do I Use an O’Reilly Auto Parts Promo Code?

To apply an eligible promo code to your order, follow these steps during the checkout process:

  1. Navigate to your Shopping Cart.
  2. Locate the Apply Promo Code / O'Rewards Reward section in the Cart Summary.
  3. Enter your code into the field and click APPLY.
  4. Verify that your Total Discount has updated before completing your purchase.

Why Isn’t My Promo Code Working?

  • Minimum Purchase Thresholds: Many codes require a specific subtotal before taxes and shipping.
  • Eligible Categories: Some discounts exclude specific brands, oil, chemicals, or special orders.
  • Delivery Methods: Free shipping codes often exclude expedited options like Next Day delivery.
  • Format: Ensure there are no extra spaces and that you have used the correct character case.

Core Charge Notice: Please note that core charges do not count toward your minimum purchase threshold. For example, if a coupon requires a $125 minimum, the price of the parts alone must meet this amount.


Does O’Reilly Auto Parts Offer a Military Discount?

Yes. All O’Reilly Auto Parts stores provide a 10% in-store military discount on most regularly priced items for active-duty and reserve service members, retired military, and veterans.

  • Eligibility: The discount also extends to immediate family members with a valid Department of Defense dependent ID.
  • Required ID: A valid military ID must be presented to a parts professional at the time of purchase.
  • Exclusions: Online orders, motor oil, antifreeze, appearance chemicals, and clearance items are currently excluded.

How Does the O’Reilly Auto Parts Low Price Guarantee Work?

O’Reilly Auto Parts is committed to providing competitive pricing every day. Our retail locations offer a low price guarantee, meaning we will price match qualifying prices from nearby brick-and-mortar competitors on identical, in-stock items with current proof of price.

  • Online Pricing: We do not currently match prices from online-only retailers.
  • Price Variations: Because taxes and promotions vary by region, pricing at one O’Reilly Auto Parts location may differ from another or from oreillyauto.com.
  • Exclusions: Clearance, refurbished, closeout, and special order items are not eligible for price matching.

Can I Use In-Store Coupons Online?

Most in-store coupons are specifically designed for use at O’Reilly Auto Parts stores and cannot be applied to oreillyauto.com orders. For in-store offers, please present a physical copy or a valid digital version of the coupon to a parts professional at checkout. One coupon is allowed per customer per transaction unless stated otherwise in the offer details.


How Do I Earn and Use O’Rewards?

The O’Reilly Auto Parts O’Rewards Loyalty Program is the best way to save on future purchases. Members earn 1 point for every $1 spent on qualifying items. For every 150 points earned, a $5 reward is automatically issued to your account. Bonus point offers are also available every month on specific items that can help you reach a reward even more quickly.

  • Sign Up: You can join for free online or visit any O’Reilly store to have a parts professional assist you.
  • Redeeming Rewards: Reward dollars can be used on most items in-store or at oreillyauto.com. Note that your purchase total must be equal to or greater than the value of the reward, and rewards expire 90 days from the date of issue.
  • Stacking Rewards: Reward dollars earned through O’Rewards can often be combined with other eligible promotions for even greater savings.
  • Track Your Points: Log in to your oreillyauto.com account or ask a parts professional to check your current balance during your next visit.
