What it does

Your Moxfield lists, priced in Czech koruna.

Moxfield shows dollar prices from US stores. This adds the numbers that matter if you play or sell in Czechia.

↑

Sell prices

What Najáda and Černý Rytíř will pay you for a card (their buyout, “výkup”).

↓

Buy prices

What they charge for it, with out-of-stock copies dimmed so you know before you click.

◎

Exact printing

Binders and card pages are matched by set and collector number, so a borderless card isn't priced like the regular one. Foil and non-foil are kept apart.

↗

One click to the shop

Every price links to that shop's search for the card, ready to sell or buy.

Prices are taken from the shops' public listings, cached for 12 hours, and matched best-effort. Always confirm on the shop's site before selling. Unofficial - not affiliated with Moxfield, Najáda or Černý Rytíř.

Install

Install in about a minute.

The extension isn't in the Chrome Web Store yet, so you load it manually (“unpacked”). It's the standard way to install a downloaded extension - see Google's guide to loading an unpacked extension.

  1. Download and unzip

    Use the download button, then extract the zip to a folder you'll keep - for example Documents\moxfield-price-extension. The browser reads the extension from that folder, so don't delete or move it afterwards.

  2. Open the extensions page

    Go to chrome://extensions - in Edge use edge://extensions. Websites can't open this page for you, so paste it into the address bar.

  3. Turn on Developer mode

    Flip the Developer mode switch in the top-right corner of the page.

  4. Load the folder

    Click Load unpacked, then select the unzipped folder - the one that contains manifest.json.

  5. Pin it

    Click the puzzle-piece icon in the toolbar and pin Buyout Prices so it's one click away. The browser may remind you at startup that a developer-mode extension is active; you can dismiss it.

Updating: download the new zip, replace the files in your folder, then press the reload ↻ button on the extension's card in the extensions page.

How to use

Open Moxfield, click the icon.

Go to a deck, binder or card page, click the extension's toolbar icon, then Add buyout prices. The popup tells you what it will do on the page you're on.
