Adding cards to watch

The Sniper only scans cards on your watch list. To add:

1. Open any card detail page.
2. Click Add to Sniper.
3. Pick the grade you're watching for (PSA 10 / PSA 9 / etc.) and a minimum margin %.
4. Save. The next 30-minute cron tick will start surfacing deals for that card.

You can have unlimited Sniper watches on Pro/Elite. Each watch can have different grade + margin settings — you can watch the same card at PSA 9 (15% margin) and PSA 10 (10% margin) independently.
