What is RevSeller Extension?

Extensive time spent to make sure you’re sourcing the best items and making the most informed decision is often a silent profit killer.

While your purchasing choices need to be based on an informed decision, streamlining data collection on products is very important.

RevSeller is a Chrome extension, meaning if you use the web browser Chrome, you can easily add it to use as a small software program that helps to customize your browsing experience.

This extension of your browsing experience allows you to see profitability with profit verification, sales rank, incomplete sales, and category on product pages as well as comprehensive sales data.

Once you quickly have this information, you are able to make educated and quick decisions regarding purchases.

How The RevSeller Extension Works

The Chrome extension is designed to help third-party Amazon sellers make informed decisions about products quickly. 

Installation of extensions on the Chrome browser is easy.

To set it up:

  1. Go to and sign up for an account.
  2. Walk through the various steps to get set up which include having payment information and your MWS keys information ready. If you are signing up for the free 30-day trial, you will not need to provide any credit card or payment information. Just fill in the basic information about your email and create a password. Before you can click the big green “Get Started Now” button, you will first need to click the box verifying you have a professional Amazon seller account and that you have read the RevSeller terms of service.
  3. In the next screen, provide your Amazon Seller ID and your RevSeller MWS Auth Token. Click the large green “Update” button.
  4. After the RevSeller account is set up, go to the Chrome store by using the red arrow under “Download the Extension”.
  5. Click “Add to Chrome”
  6. Now the extension has been added to your Google Chrome browser and will start working when you are logged into your Amazon Seller account.

Once the RevSeller extension is installed, simply view an Amazon listing by placing your mouse over the listing. An information box will be immediately generated as a pop-up with no need to leave the product page.

The information box will show:

  • The average sale price
  • The pricing history
  • How many listings of this specific item exists
  • Similar listings
  • How many of this type of product has been sold

With this information immediately at your fingertips, you can find a profitable product to sell at a competitive rate with an attractive price.

Using RevSeller To Source More Products

Before you can start using RevSeller, you will first need to have an Amazon professional seller account and then create a RevSeller account either as a free 30-day trial or as a paid annual subscription.

Once you have both accounts in place, complete Amazon Marketplace Web Services MWS setup.

MWS is an integrated web service extension API that allows Amazon sellers to exchange data about listings. It does not share any personal information on fellow sellers but does allow the Chrome extension to collect product information to return accurate and immediate results on profit margin and more.

Finally, add the extension from your Chrome browser and get ready to start fast and simple research that will rake in a healthy profit margin.

The cost of the RevSeller Chrome Extension online arbitrage tool is on an annual subscription option basis with one annual price and no monthly options available.

However, you can cancel at any time.

And, there is a free 30-day free trial period, so you can use the trial accounts before you decide to pay the subscription price every year.

Sold Out or In Stock

RevSeller also shows if a product is sold out or in stock along with any price gaps. Any product that is out of stock will be labeled as such along with the highest to lowest sell prices.

This nifty calculator will also reveal if an item is on sale and at what price, so you can easily and quickly view what items are moving well and what items are marked down.

See percentages and dollars in losses and potential revenue. This favorite tool shows the average sales price in no time at all.

Fees and Variations

One great feature is that this Chrome extension allows the seller to use the Variation Viewer to see colors, sizes, and selling prices. The variations assistant feature provides accurate numbers including variations sold and estimates of fees.

Another aspect of seeing details about multitudes of variations is that you can easily see detailed feedback and customer reviews on the product. Track reviews and additional details of data to watch the product’s performance across numerous platforms and merchants.

RevSeller works on computers and laptops but not on devices that use mobile browsers such as tablets or smartphones since the Chrome extension on phones is not yet available.

As long as you are logged into the same Amazon seller account through seller central, you can use the extension on multiple computers. If you have a virtual assistant, you can install a second copy to be used.

Investing In LEGO with RevSeller

There is more to selling online than investing and spending money on products you source to sell. When you sell an item in a specific niche, like LEGO, the time spent learning about the product may actually be enjoyable as it is an item that interests you.

However, any time spent could be costing you in the long run.

Even beginner sellers know the basics like when a new product launch happens or hitting the market when it’s hot, like selling the Star Wars collection for May 4 or a Marvel collection when a new movie releases.

But, when it comes to making a business out of online sales, it’s going to require a bit more know-how.

For instance, when trying to buy and sell individual bricks or a Minifigure, you will need to understand the market along with what price has worked for other fellow sellers and what product tends to sit for a while with seemingly no buyer interest.

Any tool that saves time while providing you with good data to help you make informed buying decisions is going to be a must-have time saver and money-making assistant.

This Chrome extension is an amazing tool that offers vital functions and saves time in giving you all the data to help you make a profitable decision as quickly as possible.

My passion for Lego began when I was a young boy and loved playing with my Lego sets. Like most kids as I grew up, I moved onto to other things and my Mom never saved my sets. (Yikes!!!!) Fast forward to when I started working the 9-5, I reconnected again with Lego and it has been a part of my adult life as an AFOL (Adult Fan Of Lego).
