How price alerts work
When and how GrailHawk notifies you.
GrailHawk scans eBay on a schedule — every 15 minutes on Free, every 3 minutes on Pro. When an active watch finds a listing at or below its target, you get both an email and an in-app alert.
No duplicate pings
Each specific listing only ever alerts you once. If the same card is still up on the next scan, we won't ping you again — so your inbox stays signal, not noise.
Why speed matters
Grails sell in minutes. On Pro, a 3-minute cadence is often the difference between the buy and the one that got away.
