Case Study: Sourcing Through Keepa




This post is designed to show the steps I go through to find a deal through Keepa and how I take it to the next level by thinking outside of the box. Please feel free to ask any questions that you might have!

Step 1: I head to www.keepa.com to search through their daily and weekly price drops. When I get to the site, I want to look at the percentage price drop (not the actual dollar amount at first). Once I find a product that catches my eye, I go ahead and click on it to take a further look. Things that catch my eye are:

1. Large percentage drops on higher priced items

2. Multipack price drops

3. Product in the categories I sell in

4. Anything that looks fun to own

As an example, I saw this product on Keepa a few minutes ago and it caught my eye due to the percentage price drop and multipack side of things. Those things peaked my curiosity and I decided to take a deeper look.

Step 1

Step 2: Next I take a look at the chart that Keepa provides once I click on the item. I am looking for a few different things:

1. A constant price history with a sudden drop

2. Signs that Amazon runs out of the product frequently

3. Any signs that point to Amazon experimenting with pricing (stairstep, skyscrapers, extended periods at a lower price)

If #1 or #2 is true, I head to step 3. If #3 is true, I head back to step #1.

This product had a very stable price and then there was a sudden price cut. It was an immediate sign to look even farther.

Step 2

Step 3: As soon as I get to the product page, I am looking for the following things to tell me it might be a good find:

1. A suppressed buy box – A price on the right hand side that is lower than the one in the middle (typically in stock by Amazon). This means you can order the product, but you won’t get charged until it ships.

2. The sales rank – I am looking for the product to be under 150,000 (my business model). We will take a look at it in more detail, but we need to take a quick look to make sure it is a product that is selling.

3. Other sellers – I want to see how many other sellers are on the listing. The lower the number, the better (you can still make money with a lot of sellers, but you face competition).

4. A complete product listing – The product needs to have a photo and be in the right category. I don’t want to sell a product where the listing is all messed up.

For this product, I see that the sales rank falls within my range and the listing look pretty good. I now move onto to step #4.

Step 3

Step 4: Now I am going to head to CamelCamelCamel to take a look at the sales rank history. This is going to give me a good idea of the demand side of the equation (price drops are great, but you need someone to buy the product at a higher price to make money). When I head to CamelCamelCamel, I am looking for:

1. Sharp drops in sales rank when a product goes back to the original price.

2. A fast spike to a high sales rank when the product is on sale

3. Long downward trending sales ranks

4. Good performing sales ranks with multiple hills and valleys within my sales rank range.

If 1-3 are true, I tend to shy away from the product. The item’s sales rank is artificially low due to the drop in price and will not sustain once it gets back to the higher price.

If 4 is true, the item is headed for my shopping cart (after I look at the ROI through my FBA calculator extension – which will be discussed in another blog post).

The example product nails number #4 as it bounces, but never goes below my acceptable range for sales rank.

Step 4

Step 5: This is the step that will make a difference in the long run. People can find the same deals that you do, but very few go the extra step (more about extra steps will be provided in future blog posts). This is the next step I took after seeing the product. Since it was a multipack, I wanted to see what other selling options (packs and single) are out there. I did a quick search and found the following (that fell within my sales rank range).

Step 5

Now not every product will be a hit, but you at least have framework to work from when sourcing items online. If you have any questions, do not hesitate to ask!

  1. This is a great post Chris. There is one thing to add Keepa and CamelCamelCamel in your daily research routine, but knowing what to look for when using those tools are key. This post illustrates what the user needs to look for and why. Thanks for this.

  2. Do you think, in this instance, Amazon is dropping the price because they were way over priced and buyers were purchasing from third party sellers? Is that also a consideration you make? It Amazon is permanently dropping the price then this wouldn’t be a good product to buy for resale, correct?

    1. Carla – That is a risk that you take in buying online. I do consider that fact and I try to look at the price history of 3rd part sellers too. Amazon typically prices competitively, but that isn’t always the case. If is a permanent price drop, it wouldn’t be a good product to purchase.
