How To Find Out How Much Inventory Your Competition Has in Stock

When you’re out sourcing, one of the things you need to consider is your competition. Say you’re out sourcing at Big Lots and come across an item with a great ROI. You research the item with your favorite scouting app and see that there are other FBA sellers selling this item. Do you join them? Or pass and look for other items with less competition? It’s something to consider when making reselling decisions.

In the past, some scouting apps were able to tell you how many of an item a certain seller had in stock, but Amazon changed the way these scouting apps get their information, and now it’s a complete mystery. Or is it?

know-your-compeitionWhen a scouting app returns the current data for a particular product, it will usually show you current prices, some of your competition, sales rank, and other pieces of information. Wouldn’t you also like to know how many of an item one particular seller has in stock? It could make a big difference in whether or not you decide to buy an item for resale. It could be helpful information to know if a few of the lower priced sellers have 5 to 10 of an item in stock before you decide to add yourself as a seller of that item. Even more critical is knowing how many of an item Amazon has in stock. With Amazon’s buying power, they could easily have hundreds or thousands of an item in stock at any given time. When Amazon has that many in stock, it’s often a good idea to pass on selling that item.

Here are the steps in how I find out how many items someone has in their current FBA inventory:

1. Go to the Amazon sales page for the item in question.

2. Click on the link that shows all of the current product offers (new, used, collectible, etc).

Amazon-Add-to-Cart3. Choose one of the current sellers and add their item to your cart.

4. Click on the “edit your cart” link.

999 in AZ cart5. Click on the quantity and change it to 10+.

6. Type in 999 (the highest number allowed) and click update.

7. If that seller has under 999 items, then it will state, “This seller only has XX of these available.”

There ya go! You now know how many of that item that particular seller has in stock at a FBA warehouse. This method works with 3rd party sellers as well as with Amazon themselves (when Amazon doesn’t have purchase quantity limits).

This information is not only good for when you are out sourcing, but also when you are pricing your items. If the three lowest priced sellers all have just 1 item in stock, then depending on the rank, you might want to price your item higher then theirs, knowing that they might sell out while your item is headed to a FBA warehouse. On the other hand, if you see that the lowest priced competitor has 100 in stock, you might want to price more competitively to get a quicker sale. It’s all about strategy and what works best for you.

Ok, now it’s time for you to put your new inventory research skills to the test! Here is an item that I want you to research. Take a look at the three lowest priced FBA sellers and let me know in the comments how many they each currently have in stock.

Don’t peek below at what others are posting. Do the research yourself. In any case, you never know if someone bought this item on the same day as you are reading this blog post, and the inventory levels have changed.

    I found the following quantities:

    I wonder if us adding it to our cart while someone else is going through this exercise will skew the results. Awesome tip, Stephen! This should be really helpful!

  2. Passionate About Books has 1

  6. I use this trick quite often. But, knowing how I do things with my FBA inventory, I think it is always good to remember that just because another FBA seller has only 1 in stock doesn’t mean 10 more aren’t on a UPS truck. And it doesn’t mean that after those 10 are sold more wont be coming. Especially on larger items or slower selling items, I don’t overstock them, but replenish them as needed.
    So it is valuable to use your wits and decide if the item is likely to be a Replenishable item that the seller can get more of at any time, or if it is likely to be a “one-off” type item such as clearance items from a big box store. I also look for a connection between the seller and the product. If the seller name happens to be the publishers/manufacturers name, for instance, then obviously they have unlimited supply.

  7. KMKB has 1 @ $9.95
    Roanoke Store has 2 @ $9.95
    Make Your Mark has 2 @ $10.15

  8. Thanks for the tip! I also found that the number left in inventory shows up when you only add one item to your cart….

  9. This is an awesome tip! Thanks Stephen!!
    Is there any way to find out how much of an item the competition is selling per month?


    • There is not a way to know exactly how many items the competition is selling per month, but you can find out some information so that you can get an idea of how many times per month an item will sell. It’s a website called You can search using the item’s ASIN on that website and it will tell you the sales rank and price history of that item. You can guess that a sale was made each time the sales rank chart has a big “uptick” in the graph. Hope this helps!

  11. 1, 1 & 4 when I looked at it. Thanks for sharing your strategy Stephen. That info along with the rank will help me make better decisions.


  12. Hi there.

    The Reseller’s Guide to Board Games – Does it cover how to find profitable boardgames online?

    You see, I’m overseas living in Sweden, and I can’t go into a physical store in the US.

    That is my only question to you.

    Kind Regards,

    Thank You Stephen for the knowledge, this will help me a great deal I appreciate you for helping us so much.

  16. I use the “How Many” Chrome extension for this very thing. It’s a time saver and you can see all the sellers inventory on the same page.

  17. Thank you Bee!

  18. Hi,

    There is an option by ‘edit listing’ to limit how many of an item a customer can buy in one order, so if a seller enters there any limit, then this trick wouldn’t tell you he’s true inventory count…

    • That’s true, but almost nobody uses this option… except for Amazon. Most 3rd party Amazon sellers don’t want to limit the number of items a person can buy from them. But it’s something to think about, so thanks for brining it up.

  19. Robert Bjorkdahl

    Great information as always! I’ve always been curious on this exact question!

  20. Robert Bjorkdahl

    Actually, I just tried it and when you put it in your cart it tells you how many they have left in stock. Great info ! Thanks !

  21. Great information! But, for the information of everybody, there is also another new Google Chrome Extension that does inspects how much inventory your competitors have in stock of your product/s. It’s called “Amzpecty”. It inspects the quantities of “ALL” product offers in just one click. You don’t have to go to every page. Cool, isn’t it? Just add the extension at this link:

  22. Wow, great extension Lloyd! Works better than anything I have seen. I have been using Keepa’s new ability to display quantity for most sellers right on the offers page (needs to be activated in the settings though). But it only shows sellers with low stock where Amazon would display “Only X left in stock” if they were in the buy box. It is still really useful though, because for the sellers that a quantity isnt shown, you know they have a lot. everyone else it is nice to see that they have 1,2,5, etc in stock at a glance. So you still get a great idea of every sellers stock, and it is right on the offers page, no extra clicking.

  23. Hey David, I just want to let you know that I got a FREE account on Amzpecty. I’ve learned that they have just launched this product just recently and that they are giving free accounts. All I did was just contacting them through their support email, because I found a minor problem, and luckily they replied to me and offered me a free account. Why not give it a try?

  24. Gene Higginbotham

    Steven, you don’t have to go thru the gyrations of adding 999 to the order;
    All you have to do is put the item in your cart and click your cart button; it will show you the item and how many the person has to sell. If it is only 1 it will say “only 1 left in stock”, If it has 9 it will say “only 9 left in stock.

    I do this on every item I buy and then buy all they have left in stock (of course if it is a good price and condition rating and SR).
    Another good thing is that the “Number” shown is for the condition you were purchasing.
