A Pokemon card price alert watches a specific card or your whole watchlist and notifies you when its price drops, spikes, or shows up listed below the going market rate. Double Holo scans the marketplace continuously for underpriced listings and arbitrage gaps, so you can catch a deal or a price move without refreshing search results by hand. Essentials delivers alerts in a daily digest; Growth adds real-time delivery for custom card alerts.
Search for the cards you care about and add them to your watchlist, or let Double Holo flag opportunities across the whole marketplace.
Pick from underpriced listings, price spikes, and raw-versus-graded or cross-marketplace arbitrage gaps, depending on what kind of opportunity you want to hear about.
Tune how far below market a listing needs to be, or how big a price move needs to be, before Double Holo alerts you.
Alerts land in your watchlist and, on the Growth plan, in Discord too, so you see an opportunity without having to be staring at the marketplace when it appears.

A card's listings change constantly: new copies get listed, existing ones get repriced, and a seller who needs cash fast will sometimes list well under market just to move it quickly. Catching that moment by refreshing search results is a losing game, since the best listings tend to disappear within minutes. A price alert exists so Double Holo does that watching for you, around the clock, instead of you doing it by hand.
Double Holo's alerts cover a few distinct situations. Underpriced listing alerts flag a card listed meaningfully below its going market rate. Price spike alerts catch a sudden jump or drop in what a card is selling for. Arbitrage alerts cover two different gaps: a graded card selling for less than the raw version of the same card, and the same card priced differently across marketplaces. Each type answers a different question, which is why the alert types are separate rather than one generic "something changed" notification.
Flagging a listing as underpriced only works if there is a trustworthy number to compare it against. Double Holo's market price for a card comes from actual recent sales, not a guess or a static list price, so an alert can say a listing is meaningfully below market with real data behind it instead of just eyeballing an old price.
Watchlist alerts are the personal layer on top of all of this: instead of every alert type firing for every card on the marketplace, you choose which cards matter to you and get alerted specifically on those. Essentials includes watchlist alerts on up to 50 cards; Growth expands that to 100 cards and adds real-time custom card alerts and Discord market alerts for price spikes, arbitrage, and buyouts, so the alerts that matter most to you can reach you faster than the standard daily digest.
