About CarParts.com
Founded in 1995 and headquartered in Torrance, CA, CarParts.com has grown into one of the recognizable names in the automotive category — and that scale is exactly why coupon shoppers should pay attention. Big retailers run continuous promotional cycles, and the codes posted on the CarParts.com homepage are almost never the most aggressive ones available. Stacked email-only codes, loyalty-tier discounts, and partner-cashback offers consistently beat the public banner promo by 5–20 percentage points.
Online aftermarket parts retailer with frequent sitewide percent-off codes and free shipping.
Why DealHarbor focuses on CarParts.com: CarParts sitewide codes typically run 10-15% off plus free shipping over $25 — competitive with RockAuto on most aftermarket parts. Our editors test every CarParts.com coupon against a real cart before it ships to this page, and we re-verify codes weekly. If a code stops working, we mark it dead within 24 hours so you do not waste a checkout flow on a promo that quietly expired.
How to use a CarParts.com promo code on this page: copy the code, click the green "Get Code" button, and the CarParts.com site will open in a new tab with the coupon ready to paste at checkout. Most CarParts.com codes apply in the cart or on the final review screen — if you do not see a coupon entry box on the cart page, look for it on the next step. Codes are case-insensitive on most retailers but copy-and-paste avoids any confusion. If a code does not work for you, please use the "Report this code" link on the coupon detail page — we use those reports to re-test within hours.
When does CarParts.com run its biggest sales? Like most major retailers, CarParts.com concentrates its deepest discounts around four windows: the spring refresh in March-April, mid-summer clearance in July, back-to-school in late August, and the November-December holiday window. Outside those windows, the best savings come from new-customer welcome codes, loyalty-tier perks, and the occasional flash promo tied to a category launch. Sign up for the CarParts.com email list and the DealHarbor alert below to be notified the moment a new code drops.
