Quick-Save Bookmarklet
Save any TCGPlayer or eBay listing to MasterGrade in one click
Drag the button below to your browser's bookmarks bar. Then, on any TCGPlayer, eBay, or 130point listing, click it to add the card to your MasterGrade watchlist with price + image already filled in. Works on desktop browsers.
Step 1 — Drag this button
Hold and drag this gold button up to your bookmarks bar. (Clicking it on this page does nothing — it's designed to run on a listing page.)
Step 2 — Use it
- 1. Open any listing on TCGPlayer, eBay, or 130point.
- 2. Click the ⭐ Save to MasterGrade bookmark in your bar.
- 3. A small window pops up with the card already filled in. Confirm + set buy/sell targets if you want.
- 4. We'll watch the price for you and ping you when it hits your target or comes back in stock.
Chrome / Edge / Brave
Show your bookmarks bar with Ctrl+Shift+B (Win) or ⌘⇧B (Mac), then drag the button.
Firefox / Safari
Drag the gold button onto your bookmarks toolbar. In Safari, enable Show Bookmarks Bar in View first.
