The Best Online Auction Websites for 2023

Best Overall : eBay

eBay is the best overall online auction website because it’s free for buyers, both seller and buyer have protections from fraud, and you’re not restricted to just the United States. You can buy and sell on eBay from most countries.

  • Buyers and sellers from all over the world

  • It’s free for buyers

  • Offers both seller's and buyer's protection

  • Seller's fees aren’t uniform across categories

  • Final value fees can be as high as $750, depending on your category

  • Displays third-party advertisements and listings from other sellers on any eBay page—including your listing

Launched in 1995, eBay is one of the oldest and largest online auction platforms, with 142 million active buyers worldwide. It’s the best overall online auction website because buyers don’t pay anything to use it unless it’s an international buyer who may have a currency conversion fee. Plus, both seller and buyer have protections in the event of fraud.  

Categories on eBay include:

  • Collectibles and art
  • Electronics
  • Entertainment memorabilia
  • Fashion
  • Home and garden
  • Motors
  • Real Estate
  • Sporting goods
  • Toys and hobbies
  • Tickets and travel
  • Pet supplies
  • Specialty services
  • Baby essentials

Anyone can sell on eBay, although there are restricted and prohibited categories. For example, you can’t sell lockpicking or locksmithing devices. eBay also doesn’t sell any of its own items, which means you have no competition from them as a seller. 

When selling on eBay, you can use photos and video to showcase your items. 

Seller's fees depend on your category, listing price, and final sale price. Fees include:

  • Insertion fees: For most categories, you receive up to 250 listings for free per month, then pay $0.35 per listing. 
  • Final value fees: Pay a percentage of the total sale price, which is usually less than 12.9% for most sellers. 
  • Listing upgrades: Take advantage of optional upgrades like international visibility, larger photos, and listing your item in multiple categories. Upgrades start at $0.10 per listing and go up to $6.00 per listing, depending on the item price.

Best for Real Estate :

We chose as the best real estate online auction website because users can buy bank-owned and foreclosed homes at auction prices. Some listings have bids starting at just $1, and some properties aren’t for sale yet but are likely to head to auction.

  • Many deals close within five weeks

  • Offers a mobile app

  • Access photos and local market data for each property listed

  • Properties sold as-is

  • Most listings are cash-only

  • Some listings require the buyer to pay a buyer’s premium of 5% or $2,500, whichever is higher

With 6.3 million registered buyers and $52 billion in sales to date, is a leader in the online real estate space. It operates in all 50 states and helps buyers purchase foreclosed, short-sale, and bank-owned residential properties quickly—many deals close in a little over a month—making it the best for real estate auctions. 

Most vacant properties have photos of both the outside and the inside. Occupied properties don’t usually show inside photos, and instead share outside and aerial views. 

Each listing is sold as-is, so a buyer should perform due diligence before bidding on a property. They should also secure financing before bidding because closing can happen quickly, often in under five weeks.  

Earnest money must be deposited within one day of auction close, which is 5% of the sale or $2,500, whichever is higher. This isn’t an extra charge as it goes toward closing costs. This differs from the buyer’s premium, which is a fee that goes to 

Not all properties have a buyer’s premium, but there is always an earnest money deposit. You can filter the listings to avoid a property with a buyer’s premium.

Best for Auto : Copart



The best online auction website for autos is Copart because you can buy vehicles for parts or in drivable condition 100% online and have the vehicle shipped to you. Many of its listings don’t require you to have a dealer's license to purchase, which means ordinary buyers can bid on a vehicle.

  • If a listing requires you to have a business license, brokers or authorized representatives can bid for you

  • Individuals, businesses, and dealers can buy and sell vehicles

  • Offers both clean and salvage titles

  • Must have a membership to bid on a vehicle

  • Fees can be high

  • It takes effort and consistency watching auctions to know what’s a good buy

There are more than 175,000 vehicles on Copart, which is an online auto auction site operating in 11 countries. It gets the nod for the best site for auto auctions because individuals, businesses, and dealers can buy and sell used, wholesale, and salvage cars, exotics, trucks, boats, ATVs, and SUVs. You can even buy and sell freightliners. Both clean and salvage titles are available on the site. 

Each listing provides detailed descriptions, photos, and conditions of each vehicle. There also is a calculator to determine shipping costs to your location. It’s not clear where Copart will ship, but there is a fair chance you’ll have to secure third-party shipping or pickup. 

Your deposit amount must be 10% of the desired bid amount if you are a Basic member. If you have a Premier membership, your deposit is just $350. Basic members have $2,000 in buying power, whereas Premier members have the buying power of up to $100,000 per day. 

Buyers' and sellers' fees depend on the final purchase price and cannot be viewed unless you are a member. Our research shows they start at $1 and go up to 12%. Heavy vehicle fees can be as high as 20%. 

There are three memberships available, and you must have a Basic or Premier package to bid:

Guest Basic $59 per year Premier $249 per year + one-time $400 refundable deposit

Frequently Asked Questions

How Do Online Auction Sites Make Money?

Online auction sites make money through listing fees, advertising fees, and buyer’s premiums. Think of buyer’s premiums as a commission—it’s a price above the winning auction price. You’ll usually find buyer’s premiums with online auction sites that use auctioneers. Other websites like eBay charge insertion fees, final value fees, and fees to upgrade listings.

What Are the Most Popular Online Auction Sites?

The most popular online auction sites include eBay, eBid, Sotheby’s, Copart,, and GSA Auctions. Most of these sites offer free buyer registration and allow winning auctions to be paid for with credit, debit, money orders, and cashier’s checks. Some even provide in-house financing options.

How Can You Tell If an Online Auction Site Is Legit?

Before buying and selling on an online auction site, look at its reputation. You can usually find real reviews on social media sites like Reddit or Facebook. Legitimate auction sites offer privacy, security, and dispute resolution. 

It’s important to understand that while an online auction site might be legit, there are unscrupulous buyers and sellers on most platforms. Check seller reviews before bidding on an item, and if you’re a seller on a platform that allows buyer reviews, like on eBay, look at their reviews, too.

What Measures Do Auction Sites Take to Protect Buyers and Sellers?

Most auction sites offer dispute resolution for buyers and sellers and limit what methods of payment are available. For example, most auction sites don’t allow wire transfers but allow payment by debit card, credit card, or PayPal. The Fair Credit Billing Act helps protect buyers when using their credit cards. 

Use the auction site’s in-house communication system if available. This way, should a dispute arise, the site can see the exchange between buyer and seller. Never take communication or payment offline to avoid fees because that limits your protection.

How We Chose the Best Online Auction Websites

We looked at 28 online auction websites available and narrowed it down to the best options based on several features and considerations. We considered fees for both the buyer and seller, the site’s online reputation, real customer reviews, and available categories. Some sites are free for buyers, and others require a membership to bid on items. Those membership fees should be reasonable.
