Description
Aggregate seller offers across all your Cardmarket wantlists in one view. **See every Cardmarket seller's matches for all your wantlists — in one click.** MarketButler is a privacy-first companion for Cardmarket. Instead of opening each of your wantlists one by one to check what a seller has, click one button on a seller's page and MarketButler fetches and merges all your wantlist-filtered matches into a single table, with a new "Wantlist" column showing which list each card came from. **Features** • One-click aggregation — a "Find all wantlist matches" button above a seller's offer table merges matches from every wantlist into one sorted view. • Wantlist column — every matched card shows which list it came from. • Full pagination — every page of a seller's offers is aggregated, not just page one. • Cart-aware highlighting — sellers already in your cart are highlighted on product pages. • Duplicate detection — a "highlight duplicates" toggle on the cart page badges cards you're buying from multiple sellers. • Mobile remove-all — restores the "remove all items from this seller" button on small screens. • Wantlist control — enable or disable individual wantlists from the popup. **Privacy** MarketButler runs only on www.cardmarket.com. Everything it reads is processed locally in your browser and stored only in local extension storage. It makes no network requests except to Cardmarket itself, and it sends no data to the developer or any third party. There is no telemetry, no analytics, and no account of its own. **Supported** Chrome (MV3, desktop), Microsoft Edge (MV3, desktop), and Firefox 140+ (desktop and android mobile).
