The 1A Advantage is, simply, peace of mind. When choosing an auto parts website, please consider the following factors:

Family Owned: We've been selling auto parts for two generations and are committed to adding you to our community of valued customers.
Faceless Company: Owned by one large corporation with a history of poor service. Before you buy check with a customer complaint site.
Auto repair videos that help: 1A Auto has created the largest collection of auto repair videos with installation instructions specific to a car's make, model and year.
Generalized/Nonexistent Videos: No installation guidance other than general instructions, if any provided. Without detailed information, auto parts installation can be frustrating and inefficient.
Highest Bizrate Ratings: a BizRate Platinum Circle of Excellence winner for over ten years - the only aftermarket auto-parts to win this award. We encourage you to check our Bizrate reviews.
No or Low Ratings: Many no longer participate in BizRate surveys because they can't match 1A Auto's quality. If they do participate, click on the Bizrate logo to see how they score, then compare to 1A.
High Quality: Trained engineers ensure parts meet strict quality standards. We have the best ratings in the industry for quality and low returns.
Whatever Part Is Available: Often drop-ship from multiple distributors and warehouses. They ship the cheapest part they can find regardless of quality.
Guaranteed Correct Part: We research each part to make certain it fits your car. Our research results go directly into our proprietary parts database, which is constantly updated for accuracy. We guarantee it!
Hit-and-Miss Parts Database: Many use a third-party database to find the right part. These often have errors - which results in a part that does not fit your car.
Same Day Shipping, Guaranteed: We stock the parts we sell. 99% of in-stock orders ship the same day. We maintain a warehouse on each coast, so you get the fastest possible delivery.
Days Later: Many outsource your order to a 3rd-party fulfillment company, typically adding up to 2 days to the delivery time. There's no guarantee when they will ship your order.
Truly Free Shipping: All shipping in the continental US is completely free.
Hidden Handling Fees: Free shipping is only offered large purchases or with hidden "handling" fees.
No-Hassle Returns: If you're unhappy (for any reason) you can return your unused item. Just fill out our easy online form.
Restocking Fees & You Pay Shipping: Offer "no hassle returns," but charge a 20% restocking fee when you return items.
Knowledgeable, USA-Based Support: Our customer service engineers are passionate about cars and must pass the National Institute for Automotive Service Excellence (ASE) certification as Parts Specialists. During business hours we answer 99% of inbound calls within a minute.
Outsourced Support: Many competitors' outsource their call centers to Asia or Eastern Europe. Customer service reps have no car parts knowledge and refer to short "scripts" written for them.
Availability Reports: The availability of each part is prominently displayed on our website. If a part that you need is out of stock, you can opt to be automatically notified when it comes back in stock.
Hit-and-Miss Part Availability: They often use drop-shippers, so they don't know stock availability in advance. After you order, you may get an email that says your part is back-ordered by weeks, or longer.
Lowest Return Rates: Despite having the most generous returns policy in the industry, our returns rate for fit, quality or damage is less than 1%, and continues to improve each year.
Many Returns: Most returns are due to parts that don't fit or are of inferior quality. Some competitors consider restocking fees as a major component of their revenue! They typically average a 10% returns rate.
Secure Interactions: We're audited daily by McAfee Secure, the leading Internet security authority, to ensure your personal information remains safe. We don't store your credit card information on our servers and we never share your personal information with marketers or anyone else.
Risky Security Practices: Some companies store your credit card information on their servers, where it's vulnerable to hacking. In addition, they may share your contact information with marketers or affiliated companies.
