One drag each, once. After this, a Copart page is one click from a filled-in calculator, and a KBB, Carvana or CarMax offer page is one click from landing in your exit price.
Press Ctrl + Shift + B to show it, drag the button up, then press it again to hide it if you prefer.
The same button does two jobs, and works out which one you need from what's on the page.
The two tabs talk directly to each other, which is how the VIN gets across without going through anybody's server. So open their site with the Open button in the calculator rather than typing the address yourself — otherwise there's no link between them and it can't fill anything in.
None of those three publishes a way to ask for an offer — it only exists at the end of their own form. A server pretending to be a browser would work for a few weeks and then quietly start returning stale numbers that still look right, which is the worst thing that can happen to a figure you're bidding against. So it reads the page you're already looking at, only when you click it, and shows you what it found before it counts.
If it grabs the wrong number, hit Cancel and use the pencil on the card to type it in.
It reads the page already open in front of you, only when you click it. It sends nothing to anyone — the vehicle details travel in the part of the URL after the #, which browsers never transmit to a server.
It reads what's on screen, so let the page load first. If a field comes through blank, type it in — everything stays editable.
This is already filled in correctly — leave it alone. It is only here for the rare case that you move the calculator somewhere else; changing it rebuilds the button above to point at whatever you type.
https://nk-bidceiling.pages.dev/, which is what the box says.
If you ever blank it out or paste the wrong thing in, put that address back.
Make a new bookmark by hand and paste this as the address — Bid Ceiling:
