What is GrailHawk?
The 60-second overview of how GrailHawk works.
GrailHawk is a real-time price tracker for trading cards and collectibles. You tell it the card you want and the most you'll pay; it watches eBay around the clock and alerts you the instant a matching listing lists at or below your price.
You do the valuation once. GrailHawk does the watching forever — so you never refresh listings again or miss a deal while you sleep.
