12 Places to Sell Auto Parts Online, and What Each One Costs

Ask where to sell online and you’ll get a list of marketplaces. Parts don’t work that way. A buyer shopping for a cabin filter needs to know it fits a 2017 Tacoma, and a channel that drops that information will cost you returns whatever its fees look like.

The question worth asking is narrower: which channels handle year, make and model data, which ones can quote freight on a hood, and which ones put you in front of people who already know what a core charge is. US aftermarket parts moved roughly $44.6 billion online, with the Auto Care Association forecasting 5%-plus compound growth through 2030. There’s room for you in that number on several channels at once.

Here are twelve, grouped by the job each one does.

Channel You Own

1. Your own store

Everything else on this list rents you an audience. Your own site’s the only place where you keep the customer, the data and the margin.

That matters more in parts than in other categories, because the tools buyers need are the ones marketplaces keep locked down. Year/make/model search, VIN lookup, a saved garage, fitment notes on engine size and brake type, core charges, freight quotes at checkout: on your own store you build those around your catalog. Fitment search tools turn a shopper still guessing at what they need into one who buys without calling you first.

Treat the store as the hub and the marketplaces as spokes. Your catalog, pricing rules and stock live in one place, and each channel pulls from it.

Big Three Marketplaces

2. eBay Motors

eBay’s where parts selling online grew up, and it still has the deepest fitment plumbing of any marketplace. You can attach up to 3,000 year, make, model, trim and engine combinations to a single listing, adopt eBay’s parts catalog by brand plus MPN or GTIN to pull details in automatically, or load compatibility in bulk with the Master Vehicle List through Seller Hub reports.

Get that data right and eBay backs you up. Under eBay Guaranteed Fit, when a buyer’s saved vehicle matches the compatibility you entered, eBay covers the return label if the part turns out wrong. Tires and wheels sit outside that program, though the compatibility checkmark still shows.

Fees on Parts & Accessories run 13.6% of the sale up to $7,500 per item plus 2.35% on anything above it, with a per-order fee of $0.30 under $10 and $0.40 over. Store subscriptions and insertion-fee allowances change the math on high-volume accounts.

3. Amazon

Amazon brings more traffic than any automotive site, and it asks for discipline in return. Automotive and Powersports carries a 12% referral fee, and the category runs on Amazon’s own data model: clean part numbers, brand registration, and fitment loaded so Your Garage filters surface your listing to the right vehicle.

The hard part’s the buy box. Several sellers compete on one product page, and price plus Prime delivery decide the winner. For commodity filters and pads, that’s a race you might lose to a distributor selling at cost. Branded, hard-to-source and performance parts hold up far better.

Keep stock synced tightly. Amazon measures you on cancellations, and overselling a part you’ve already sold elsewhere is the fastest way to a suspended account. A multi-channel integration that pushes stock from your store out to both Amazon and eBay is worth setting up before your first listing goes live.

4. Walmart Marketplace

Walmart’s the one a lot of parts sellers skip, and the economics deserve a look. There’s no monthly or setup fee, Automotive & Powersports pays 12% and Tires & Wheels pays 10%. On a $200 order that undercuts eBay.

Competition’s thinner than Amazon’s because approval takes longer and plenty of sellers skip the paperwork. Walmart also runs tire installation through its own auto care centers, and that gives wheel and tire sellers a fulfillment story the other marketplaces lack.

Here’s how the three compare on a $200 part:

Channel	Fee on automotive parts	Fee on a $200 sale
eBay Motors	Fee on automotive parts	13.6% + $0.40 order fee	Fee on a $200 sale	$27.60
Amazon	Fee on automotive parts	12% referral	Fee on a $200 sale	$24.00
Walmart	Fee on automotive parts	12% referral	Fee on a $200 sale	$24.00
Your own store	Fee on automotive parts	Payment processing only	Fee on a $200 sale	roughly $6

Those marketplace numbers buy you demand you didn’t have to create. The gap between $24 and $6 is what you’re paying for it, and it’s why the sellers who grow move repeat buyers onto their own site.

Channels That Feed Your Own Store

5. Google Shopping and free listings

Google’s the shortest path from a search to your product page. Merchant Center gives you free listings that can appear free on Search, Images, Lens, YouTube, Maps, the Shopping tab and Gemini, and the feature arrives switched on by default.

Parts feeds need care. Vehicle fitment has no dedicated Merchant Center attribute, and the work goes into titles, GTINs and structured product data on the page instead. Our walkthrough of Merchant Center setup covers the approval problems that catch automotive catalogs.

6. Facebook Marketplace and Shops

Marketplace is where used parts, takeoffs and wheel sets move locally, with cash changing hands and no freight bill. Listing is free, and a seller clearing out a shelf of pulled OEM parts can do real volume there.

Shops is the other half: a catalog connected to your Facebook and Instagram pages, with checkout either on Meta or on your site. Send it to your site where you can. Enthusiast groups do the selling for you anyway, and a Mustang forum crowd that trusts you is worth more than a one-off local sale.

7. TikTok Shop

Short video sells accessories: light bars, floor liners, shift knobs, wraps, detailing kits. An install clip that shows the part going on a truck does more than a spec sheet manages, and the checkout sits inside the app where the video plays.

Keep it to visual, universal-fit products. Anything that needs a fitment check or carries hazmat rules belongs somewhere you control the page. Pricing matters too, since the audience skews toward impulse buys under $50.

Buyers Who Come Looking for Specific Parts

8. Etsy

Nobody shops Etsy for brake pads. They do shop it for restoration pieces, reproduction badges, period-correct knobs, custom gauge faces and shop art. If you machine small runs or sit on NOS trim for cars that stopped production decades ago, the audience is already there and it’ll pay for scarcity.

9. Hemmings

Hemmings has served the classic-car world since the 1950s, and its classifieds put you in front of restorers hunting one part for one project. Volume’s low and intent’s high. Somebody rebuilding a ’66 Chevelle will pay for the right manifold and read your description twice before they do.

10. Car-Part.com

That’s the channel general roundups leave out. The site indexes recycled inventory from auto recyclers across North America, 120 million inventoried parts that body shops, insurance adjusters and DIYers search by part, grade and distance. It’s been running since 1998.

Recyclers list through Car-Part’s own inventory software and can search other yards’ stock when a part’s missing from their shelves. For a salvage operation, being in that index matters more than having a storefront. For a parts retailer it’s a sourcing tool, and a way to check what used alternatives are doing to the price of your reman line.

11. Craigslist and local pickup apps

Freight’s what kills margin on bumpers, hoods, doors and engines. Local listings dodge it completely. A hood that’d cost $180 to crate and ship goes for cash to somebody who drives over with a pickup.

Keep it for heavy, low-value and hard-to-pack items, and treat it as a release valve for inventory your shipping rules make unprofitable. Shops moving from a counter to a website often keep this channel running alongside, and our guide to moving a parts store online has more on running both.

Wholesale Side

12. Your own B2B portal

Repair shops, fleets and resellers order all week, and they’d rather do it in a browser than on hold. A portal with group pricing, restricted catalogs, part-number quick order and live stock gives them that, and it costs you no marketplace commission at all.

Shops buy on availability and accuracy before price, and they reorder the same parts month after month. A B2B ordering setup turns those phone calls into orders.

Tie it to your warehouse distributors and those orders route themselves to whichever location can fill them.

Picking Two or Three

Running twelve channels badly beats running none, but only barely. Pick by what you sell.

If your catalog is aftermarket parts with real fitment data, start with your own store plus eBay Motors, then add Google free listings. If you carry brands people search by name, Amazon pays off and Walmart’s worth the approval wait. Salvage and used OEM belongs on Car-Part.com and Marketplace. Restoration and reproduction parts want Etsy and Hemmings. Accessories that look good on video want TikTok. Sell to shops, and the B2B portal will out-earn the marketplaces on this list.

Two things decide whether any of it scales: one source of stock and one source of fitment. Catalog data management that holds ACES and PIES properly feeds every channel from the same place, and it keeps you from maintaining four versions of the same part number.

Where to Start

Pull last quarter’s orders and sort by channel and by margin after fees. Plenty of sellers find one channel carrying the volume and one quietly losing money on oversized items.

Then list twenty products on one new channel, not two thousand on three. Load the fitment data properly, watch returns for a month, and scale what holds up. X-Cart pricing starts at $499 a month with marketplace integrations included, if you want the store and the channels running from one admin panel.

The marketplaces will keep sending you first-time buyers. Your job’s to make sure the second order comes to you direct.
