When a source changes, you hear first
The Amazon sources of your live listings are watched in two ways. The Seller Library Tracking System checks products about every 12 hours, even with your computer off. With the Chrome extension you can choose 1, 2 or 4 checks a day; for that, the computer and Chrome need to be open.

01Steps
How it works
Two ways to track
The Tracking System runs on the server and doesn't wait for your computer to be on. Extension tracking reads from your own browser at the frequency you choose. Both can be used for the same product.
Unknown is a result too
If Amazon doesn't show a page or asks for a verification, no value is guessed. The product is marked 'unknown' and the time of the last real check is kept.
Rises and drops, your choice
You choose in Rules what happens when the source price rises or drops. In Rule mode the price changes between the floor and ceiling you set; a change beyond your limits waits as a suggestion.
Capacity from your package
How many products the Tracking System watches at once is your package's tracking capacity, shown on the Pricing page.
02What changes
The work done by hand is wiped away; one flow takes its place.

03Needs and limits
What to know before you start
What it needs
- Seller Library Tracking System Runs with your computer off, for as many products as your package's tracking capacity.
- Extension tracking The computer and Chrome must be open; 1, 2 or 4 times a day.
Where it stops
- Amazon prices and stock can vary with the US delivery region.
- Reading stops on a page that asks for a verification; there's no attempt to get around it.
- Tracking never deletes an eBay listing on its own.
In the packages
The monthly new-listing allowance, tracking capacity and how many stores you can connect depend on the package. The allowance is shared by all your stores.

YouDoes tracking work with my computer off?
SellyFor products in the Seller Library Tracking System, yes: they're checked on the server about every 12 hours. Extension tracking needs the computer and Chrome open.
SellyIt means the price or stock couldn't be read reliably in that check. SellerLibrary doesn't guess; the time and value of the last real check are shown separately.
