  description

  CardBeast Bulk Lister puts your CardBeast-scanned cards onto CardMarket for you, so you never type a listing by hand again.
  
  How it works:
  1. In the CardBeast app, scan your cards and export the CardMarket CSV.
  2. Open this extension and upload that CSV.
  3. Click through to CardMarket's "List Mixed Products" page. A CardBeast panel appears there.
  4. Run a Dry run first to check every card matches, then List for real.
  
  Features:
  - Lists across every expansion in a single pass.
  - Dry-run mode verifies each card is found before anything goes live.
  - Human-paced listing with built-in delays, so the process stays natural.
  - Skips and reports any card it cannot match, instead of guessing.
  
  The extension only reads the CSV file you upload, locally in your browser. It does not collect, send, or store any personal data.
  
  Requires a CardBeast account to export the CSV. Learn more at cardbeast.io.

  Features:

  - Dry-run mode verifies each card is found before anything goes live.
  - Human-paced listing that mimics real human behaviour: it types each field at a natural speed, varies the timing between cards, adds short pauses and the occasional longer break, and slows down on its own if the site is slow, so it behaves like a careful seller listing by hand, never a bulk machine hammering the page.
  - Skips and reports any card it cannot match, instead of guessing.
  - Runs entirely in your own browser on your own logged-in CardMarket session, at a pace that stays courteous to CardMarket and respects its rules.
