Sale-by-sale evidence
Every price links back to the actual completed eBay sale it came from. No estimates, no invented numbers — just verified sold comps you can click.

Your collection total reflects everything you own, priced from real sales rather than asking prices — with full history behind each value.
Smarter sell decisions
Compare a card's history against our Sell Now offer before you accept, so you always know whether to cash out or hold.
Early access to new tools
Pro members get new Demondex features — pack tools, deeper market data and exports — before anyone else.

Every plan starts with a free 30-day month — we don’t ask for a credit card to begin. Add payment details only if you choose to continue; if you don’t, the trial simply ends and you’re never charged.

Is the first month really free?
Yes. Every new Pro membership starts with a 30-day free month on either plan, and we never ask for a credit card to begin. You only add payment details if you decide to keep Pro after the free month.
Where do the prices come from?
Only completed, verified sales of the exact card code. If we have no qualified sale for a card yet, we show “Price pending” rather than guessing.
What happens to my cards if I cancel?
Nothing is deleted. You keep your collection and unlimited tracking; only the full price history and sale evidence lock until you resubscribe.
Can I switch between monthly and yearly?
Yes. Manage or change your plan any time from the billing portal on this page.
Do you price the Special Mini series?
Mini cards rarely sell individually, so they stay unpriced until real sold comps exist. We never invent values.
