Best Online Arbitrage Tools for Amazon Sellers

Online Arbitrage remains one of the most potentially lucrative forms of Amazon businesses in 2023. In this post, we’ll look at our list of best online arbitrage tools for Amazon sellers, including a handful of free tools to help your business grow and save money.

What is Online Arbitrage?

Online Arbitrage is the practice of sourcing products online through various retail sites and reselling them on the Amazon Marketplace. Online arbitrage sellers target many products, from books to beauty products, pet toys to pantry staples. This contrasts with selling private label products with your brand, which are unique to you.

A common question when talking about online arbitrage is whether money will be made and, if so, how. Shouldn’t the prices at all the various retail stores be the same? The answer to that is: sometimes. The vast majority of products sold on various online marketplaces and retailers generally land within the same price range.

Online Arbitrage finds its niche and success in exploiting deals and coupon codes. Some retail or online stores may be running a promotion or trying to move all of their existing inventory–there’s potential for real money to be made.

Conversely, most retailers may sell a product for a certain amount. Still, the selling price for that exact product on the Amazon marketplace is much higher, allowing for potential Online Arbitrage finds its niche and success in exploiting deals and coupon codes. Online Arbitrage finds its niche and successfully exploits deals and coupon codes for substantial profit margins.

That price difference is where all the profit margin lives. Most people shopping online and on Amazon don’t usually check all the sites for the best deal. Amazon has created an ecosystem of one-click, no-thought purchasing. It doesn’t matter that Amazon isn’t the lowest price–it’s the most convenient online shopping option, end of the story.

Types of Online Arbitrage Tools

The right online arbitrage tools can help find products with significant profit margins. Often these products are on sale at other retailers and priced higher on Amazon.

Flexing the array of tools for finding profitable products is the key to being a successful online arbitrage seller.

Coupon Portals

Finding profitable deals requires knowing which online retailers are running good sales–they don’t always make their discounts known to the public. Coupon portals aggregate discount codes from across the Internet to land you a secretly excellent deal on a particular purchase.

Cash Back Sites

Earning cash back isn’t limited to your credit cards. Cash-back sites often exercise affiliate programs or referral agreements with retailers to split the commission they earn when you purchase through their portal.

Deal Sites

If you know where to look, things people shop for rarely sell at regular prices. These portals are chock full of products from all categories and niches and often highlight deals for products that don’t often go on sale or, if they do, are discounted much more than usual. A lot of these sites are community-sourced, too.

Full Software Suites

Sometimes it’s best to pay the pros for your hard work. They’ve built powerful tools that pull in all the sales rank data, crunched the monthly sales numbers, comb the retail outlet(s) and online store(s) of your choice, and spit out only products that can make up your profitable inventory.

These tools are Internet-based, so having an Internet connection is only required when feeding them data or checking out the results. They’re doing the hard part on their end without any intervention from you.

Browser Extensions

Regarding Internet connections, browser extensions play a unique role in online arbitrage. They sit within your browser, observing the pages you visit, and pointing out helpful things like Amazon sales rank, whether discounts exist, the price history and sales trends, and more.

Profit Calculators

Having accurate profit calculations is critical. The last thing you need is to have a room full of chew toys that you bought for $8 each, but it turns out they only move when sold for $7 on Amazon.

Likewise, the other room full of chair cushions will move, but how much effort did you have to put into them for a mere $.30 profit on each? Be able to quickly see whether the purchase you’re about to make comes with a big enough price difference to make it worth your time.

Repricing tools

Once your product is up for sale on the Amazon marketplace, it’s essential to ensure you’re staying competitive with your prices. Chances are, you’re not the only seller of your product. Repricing tools help you land the buy box more often by tweaking your pricing. The buy box price is the price most folks see, so landing that space is critical.

Aura is the fastest, most powerful, and yet most straightforward repricing tool I’ve come across on my Amazon journey.

We even ran a podcast together called Welcome to Growth. The show is no longer in production, but it taught me that his mind is fantastic. You can see it in how Aura works, too. Intelligent decisions about how to reprice when, workflows for repricing only under certain conditions, and more.

This all sounds complicated, but Aura makes them dead simple. Aura is also the fastest to adjust prices based on other market activities.

Coupon Finders (Honey, Rakuten, Camelizer, InvisibleHand)

There are dozens of coupon-finding tools, but Honey is my favorite. It sits quietly in your browser as an extension and can alert you when it seems you’re on a product that may have a discount code applicable to it. This pairs nicely with purchasing products found using online arbitrage tools because not only do you have yourself a profitable product, but you’re also saving a bit extra on the purchase, too! Extra profit!

Rakuten, Camelizer, and InvisibleHand are also great options worth looking at.

Cash Back Sites (Swagbucks, MyPoints, Wikibuy)

Taking the combination of tools even further, sites like Swagbucks, MyPoints, and Capital One Shopping (formerly Wikibuy) are great for collecting a few % cash back on the sites you’re purchasing products from. When executed correctly, online arbitrage software, coupons, and cashback earnings can be lethal for acquiring products to sell on Amazon, keeping more money in your pocket, and having higher profit margins than your competition.

Some argue that online arbitrage isn’t legal. It’s a bit more nuanced than that.

Buying and selling goods is legal if purchased legally and not counterfeit. Even though online or retail arbitrage is legal, sales of these goods can cause headaches, such as censorship of products and IP violations.

The Grey Area of Trademark and Intellectual Property

This is where we enter the legal arguments of breaking the traditional manufacturer-distributor-retailer model by turning a retailer into another distribution layer. It’s worth pointing out that laws vary by country and jurisdiction, so check with yours beforehand.

Fundamentally, we have the First Sale Doctrine in the United States, more formally known as 17 U.S. Code § 109. Here’s how the United States Justice Department describes it:

The first sale doctrine…provides that an individual who knowingly purchases a copy of a copyrighted work from the copyright holder receives the right to sell, display or otherwise dispose of that particular copy, notwithstanding the interests of the copyright owner.

In plain English: if you bought a book, briefcase, or barbeque, you can sell that thing to someone else for whatever you want. The original manufacturer of the item received compensation when they sold it to the next person (be it a distributor or retailer) and cannot expect further compensation.

For example, I paid for the travel books on my bookshelf. The publisher received their money for those copies, so I am free to sell those specific copies to whomever, for whatever price. The publisher has no say in that exchange.

Here’s where things get a little murky. While the law (in the United States, anyway) protects you from the original creator in the event of resale, it does not afford any protection or guarantee when selling on Amazon or another online marketplace. These marketplaces can and do have rules and policies regarding the sale of goods and using trademarks to do so.

Some brands can and do, claim counterfeit if a seller of their products on Amazon is not “authorized” or permitted to sell their goods on that marketplace. Amazon sellers all run into this at some point unless they sell unique private-label products they’ve created. These brands often argue that it cannot be proven the product is theirs because the seller is not a part of their recorded distribution chain.

However, because it is commonly known that major retailers like Target, Walmart, and the like don’t sell counterfeit goods, providing documentation that the products were purchased from a reputable location often helps counter those claims.

Claims of Trademark infringement a harder to argue, though not impossible. Trademark enforcement was meant to prevent confusion about the source of goods bearing specific trademarks. Still, brands can and will often wield this power to eliminate sellers of their products on the Amazon marketplace.

Fair use laws are supposed to protect against this, but it’s not as clear-cut as we’d all appreciate, and there’s open room for trademark holders to argue what fair use of their brand names means.

With all things about legal topics, I don’t have a clear answer to all this–I am not a lawyer. Tackling potential counterfeit and trademark claims when selling products sourced via online arbitrage is something you may run into in the future.

Suppose there’s one thing to take away from this. In that case, it should be that doing your homework, making sure the brands are “safe,” and is ready to potentially liquidate when that dreaded cease & desist letter or notification email from Amazon of a counterfeit strike arrives are all a part of the game.

Further Reading

Because this a nuanced topic, we’ve put together a guide that tries to determine if retail arbitrage is legal that dives more specifically into whether arbitrage (retail and online) is legal technically and the nuances that make the practice not so free and clear.

Is Online Arbitrage Profitable?

alexander mils lCPhGxs7pww unsplash
When executed correctly, online arbitrage can be an incredibly lucrative form of selling on Amazon.

A well-run online arbitrage business is profitable. It’s not a business model for the faint of heart–it requires constant movement and sourcing. The proper use of online arbitrage tools we’ll cover below extensively ensures you’re landing profitable products. Defining boundaries and setting rules during product research can play an almost as significant, if not more prominent, role.

How to Find Profitable Products

There are three things I like to always keep in mind when I’m researching products:

Sales Rank

There could be a good reason if the product isn’t moving on Amazon. Knowing how quickly a product sells plays into how much you buy and the margin you’re going after. A fast-moving product can withstand a smaller margin because it’s made up of volume, whereas a slower-moving product with a higher price can potentially afford to sit around for longer.

Margin Compared to Cost

I’ll cover this more in the next section because there’s a lot to find the right price and ensure money is being made. We’re looking to operate a profitable business model using profitable products. We’re not selling on Amazon everything we can find, and we hope for the best here.

Extra Costs Specific to Product Categories

This one is vaguer, and its importance is entirely up to you. In this case, I’m thinking about everything else that I might be spending money on related to the products I’m sourcing:

  • Do I need to do additional prep work like bubble wrap, poly bagging, etc. (or pay someone)?
  • (For online arbitrage) What’s the risk of a damaged product arriving to me? How easy is it to return bad units?
  • Does the product have an expiration date? If I can’t sell them all before they expire, what do I do with what’s left?
  • Will the product’s size affect how much I pay for shipping costs?
  • How many are other online sellers selling this same product? Will I have to mark down my price more than I originally planned to compensate for the extra competition?

What is a Good Profit for Online Arbitrage?

As a general rule of thumb, the minimum I’m looking for in profit on the base item cost is 20-30% for fast-moving items and 100% for slower items. Defining these thresholds is entirely up to you; there’s no hard-fast limit. A thought exercise to help you decide what “fast” means: How quickly do I want this money back to re-invest?

It might seem counter-intuitive to want to make less money on a product, but this idea shines and makes the most sense when we look at compounding.

Here’s an example: I acquire 100 books with a purchase price of $5 each, for $500 in total. I can sell all 100 books within 30 days at $7 each for a $200 profit or 60 days at $8 for a $300 profit.

I make the same purchase when I run out in both circumstances. After 6 months, in the first scenario, I purchased 600 books and made a total profit of $1,200. In the second scenario, I purchased 300 books and made a profit of $900.

There’s always a threshold where the higher profit margin is better–in this case, if I sold the books for $9 each, the profit would be the same.

Outside of this, I also have to factor in various fees. As an Amazon business, specifically Amazon FBA, I’m looking hard at storage fees and how they impact the extra costs of keeping inventory around.


We covered a lot in this guide, but with this information, you’ll be better prepared to tackle online arbitrage’s massively lucrative and profitable world. Finding profitable deals and building a robust inventory is easy with the right tools. Online arbitrage tools can be overwhelming for new Amazon sellers, but their flexibility, prowess, and specialization make them critical to success.
