First a few comments: Sellernaut does not guarantee that any model referenced herein, or the data on which it is based, is foolproof. What we provide are mere guides, helping you (and ourselves) to hopefully make better buying decisions. Upon registering and logging in, you have the option to enter in both cost of your item and its targeted FBA send in cost, if applicable. What we've developed to date is always evolving and, we hope, improving. To that end, we are often making changes to the software and, so, you can expect some things to look different from time to time.

Please explain the data you call and format.

Title, ASIN, sales rank, weight, and publication are formatted in the header/search bar area.. Images can take up a lot of room, particularly on a mobile device, but because of non-ISBN search features (featuring up to 8 results), we think it's important to have an image. In this way, if for example users have voiced or texted in a title in hand, they can see if the item image matches up.

Weight serves as an important reference point for shipping costs, both sending to an Amazon warehouse and if the item is fulfilled by Amazon.

Sales Rank is also an important reference point, but for us it is not always instructive. Sales ranks are dynamic, i.e. they're constantly changing. A seller can make poor decisions if the Sales Rank is either high or low. Like other data points, Sales Rank serves as a guide in context.

Seeing a publication date can further inform your buying decision. For example, if an item is a particularly older book and has a lot of value then you most certainly probably have something that might retain its value. On the other hand, if a textbook is more than a few years old and it only has decent value during textbook season it might be something you wouldn't want to hold on to for long. Likewise, a recent hardcover book of fiction might also have questionable long-term value.

Current AZ offers and their associated data

New and Used offer totals.

Competitive Price (comp) is, generally speaking, an FBA offer.

All FBM Used items are total prices. (FS) stands for "Free Shipping."

If there's a Competitive New offer, it will show and it is not necessarily always Amazon's.

We are currently calling the lowest 20 offers in total. This call has a very restrictive throttling rate and, so, we may need to resort to a call that has more limited results.

What do you mean by "buyback?"

For those unfamiliar with buyback or trade-in on Amazon, it was typically (and still is) a way for college students to sell back their books, often to a university bookstore, often at a large discount but at least in a way to recoup or mitigate their costs of education. Today, there are tens of online buyback companies who often buy not only textbooks but other non-fiction and literature for prices that you would not be able to equate selling FBA or FBM.

Accordingly, the first line under Buyback shows if Amazon is buying it for trade-in (Amazon gives store credit, not cash). We do not format any Amazon trade-in price if it's not at least $1.00.

The second result is for "TB" is one of our favorite buyback companies because they often pay good prices for classics, not just "textbooks."

"BM" is for another of our favorites -

What do you mean by "sales history?" Is that my sales history? How is this different from Keepa or camelcamelcamel?

This section links to our Amazon sales history. We show Sales Count, Avg Price for that Sales Count, and the last recorded purchase (sometimes the data doesn't update as readily as we like). Knowing Sales Historical Prices is a better measure, we believe, than simply whether items have sold, a la Keepa and camelcamelcamel.

If you want to hook up to your own Sales History using Sellernaut, please let us know.

Can I make non-ISBN searches?

Yes. 10-digit and 13-digit ISBN searches automatically go to the single item page, but a non-ISBN search (title, author, product) will call up to eight results on the multi-item page with according images, if provided by Amazon. UPC searches (12 digits) do not currently work with the software but a fix is coming. The below partial screenshot shows eight results for an item.

Mousing over items will highlight them. Click on "More Data" by item and it will be submitted in the Search Box.

Where do you get your data?

Almost all data is called via Amazon's MWS API.

Seller credentials are ours. We don't currently have access to Amazon's bulk data. All data is "live" and not via a database; therefore, you will need a good connection to use this software. In the near future, we may need to implement a developer framework where users who want to use advanced features would need to have an Amazon seller account for us to make MWS API calls on users' behalf. Currently, no sellernaut user is required to have an Amazon seller account.

May I do unlimited searches?

Yes. The only caveat is this: again, Amazon throttles calls to the lowest priced offers (20) which is the best call and which we currently use. Due to stated throttling issue, the time may come when Sellernaut will ask users to log in and provide their Amazon MWS credentials to use the software, otherwise there could be delays in requests. Using your own credentials is not unlike what users currently provide to scouting service providers and/or other service providers who access Amazon data. Of course, this means that you would need to become an Amazon pro merchant.

Will Sellernaut always be free?

There's a good chance it will be free for the foreseeable future. It will certainly be free while we continue to tinker with its functionality.
