Deal Radar alerts
eBay tells you a listing exists. Wildcard tells you it is underpriced.
eBay tells you a listing exists. Wildcard tells you it is underpriced. Type the card, confirm your address once, and the daily scan emails you when a listing prices under real completed sales, with the fair value it was measured against. Free, no account, unsubscribe in one click.
Watch a card
Name it exactly: year, set, player, card number. The scan refuses everything that is not that card.
One confirmation link, then at most one email a day, and only when a listing is under comps. Unsubscribe in one click from any alert. See what an alert looks like →
Where an eBay saved search stops
| eBay saved search | Wildcard Deal Radar | |
|---|---|---|
| What triggers it | A new listing matches your keywords. | A listing is priced under the fair value of THAT card, measured from completed sales. |
| What it knows about value | Nothing. "Cheap" means cheap against the seller's own ask. | The fair value, the sample of sales behind it, and how much the listing sits under it. |
| What it filters out | Only what your keywords exclude. | Lots, empty boxes, packs, reprints and customs, a different card number, and any watch whose comps are too thin to trust. |
| How often | At most once a day, when there are new matches. | Once a day, and only when something is under comps. A quiet inbox means nothing was. |
| What it costs | An eBay account. | An email address. No account. Three watched cards free. |
| When it goes quiet | Silently, when your filters match nothing. | It tells you: a watch whose comps stop being trustworthy is paused with the reason logged, not left alerting on a bad number. |
The speed of an alert is a contested axis, and not the one this is built on. The scan runs once a day, like eBay's. What it adds is the judgment: the number a listing is measured against, and the honesty to say nothing when nothing is under it.
What an alert looks like
A real one. These three rows were delivered by the scan on 2026-09-15, at these prices, against these fair values. The listings have since moved on, so the titles are not linked.
Subject: 🔥 3 deals found on your watchlist
Flagged this week
The live feed opens once the scan's identity gates have run clean for a few days against the alert ledger. Until then, the sample above is the honest version: real alerts, chosen by hand.
Questions
How is this different from an eBay saved search?
A saved search is a keyword match: it fires when a listing contains your words, and it has no idea what the card is worth. A Deal Radar alert fires when a listing is priced under the fair value of that specific card, measured from completed sales, and it shows you that fair value in the email. It also refuses lots, packs, reprints, customs and a different card number, which a keyword match cannot.
Why once a day and not instantly?
Because the judgment is the product, not the speed. The scan runs daily, prices every new listing against completed sales, and sends one email covering everything it found. Instant delivery by push and Discord is the part Pro will add; the daily email stays free.
What is "fair value"?
The value of that card from recent completed sales, with a confidence score built from how many sales there were and how tightly they agree. A watch whose comps are too thin or too scattered is paused rather than allowed to alert on a number nobody should trust.
Do I need an account?
No. Type the card and an address, click the one confirmation link we send, and the watch is armed. Nothing is sent before that click. Every alert carries a one-click unsubscribe.
What should I type?
The year, the set, the player and the card number: "1986 Fleer Michael Jordan #57" rather than "Jordan". The more exactly you name the card, the more exactly the scan can refuse everything that is not it.
Why did my watch go quiet?
Usually because nothing listed under comps, which is the normal state for a fairly priced card. Occasionally because the comps behind it stopped being trustworthy, in which case the scan pauses the watch instead of guessing. Either way, a quiet inbox is the honest result, not a broken one.
