Frequently Asked Questions

What's the free shipping threshold?

Most Ship to Home orders of $35 or more (excluding core charges) qualify for free standard ground shipping. Oversized items, some Alaska and Hawaii shipments, and out-of-stock items don't qualify.

Can I return a part I already installed?

Refunds within 90 days may be refused if the part has been installed or used, even if it's in working condition. Uninstalled returns need the original receipt, original packaging, and all included materials.

How do I earn O'Rewards points?

You earn 1 point per dollar automatically on qualifying purchases once you're signed into your account, whether you're shopping in-store or on OReillyAuto.com.

Where do I enter a code at checkout?

On the cart page, look for the "Promo Code or O'Rewards Reward" box, enter the code there, and the total updates once it's applied.

Can I combine more than one code?

Promo codes like PERKS20 generally can't combine with other certificates or discounts. O'Rewards dollars are the exception, they can often stack with an active promotion.

Does O'Reilly price match other stores?

Yes, in-store only, against nearby brick and mortar competitors on identical, in-stock items with current proof of price. Online-only retailers, clearance, and special order items aren't eligible.

Can I return a battery once it's been installed?

No. Batteries can't be returned once installed for any length of time, unless a store tests it and confirms it's defective.

Saving Guide

Stack the promo code with O'Rewards. PERKS20 excludes combining with other certificates or offers, but O'Rewards dollars are the one exception that can still apply on top, so redeem points on the same order if you have a balance.

Buy online, pick up in-store to skip shipping entirely. Free Ship to Home only kicks in at $35, but Buy Online, Pick Up In-Store has no minimum and no shipping cost at any order size.

Time bigger purchases around bonus point months. Bonus point offers on brands like Mobil 1 and Castrol rotate monthly and can be 2x to 7x normal points, worth checking before a routine oil change purchase.

Bring proof of a lower local price before you buy. The low price guarantee only works in-store with current proof of price from a nearby competitor, so it's worth screenshotting a competitor's price before heading in.

Watch the return window on installed parts. Refunds on installed-but-working parts can be refused even within 90 days, so confirm fitment before installation if there's any doubt.

Shopping Guide

Double check part compatibility before buying. O'Reilly's own guidance recommends confirming every vehicle detail and comparing the part photo to your old part before installation, catalog errors can occasionally list an incorrect part.

Understand core charges before checkout. Parts like batteries and alternators often carry a core deposit that's refunded only when the old part is returned, factor that into your total before you buy.

Check warranty length by product type. Most parts carry a one year replacement warranty, but commercial vehicle installs drop to 90 days, and some parts like fuel pumps or A/C compressors need specific companion parts replaced to keep the warranty valid.
