We gather the cards, target prices, and alert types collectors actually want.
Price alerts
Tell Card Signal what card you want to watch.
This is the first version of alerts. Submit a card search and target price so we can build the alert queue before turning on automated emails.
Roadmap
How alerts will work
Active listings can use official eBay APIs. Sold comps need approved or licensed access.
Automated email will only launch with proper unsubscribe and sender compliance in place.
