Your counter sells cards every day. No price tool has ever seen it.
Every tool you’ve ever paid for tracks eBay and the auction houses. So do we. The only sale no tool can see is the one that crosses your counter — and that’s the one we weight highest.
The movement
The CompIQ Alliance is hobby shops banding together to fix that. Members send anonymous sale lines — just the card, the price, the date — and the alliance turns real counter sales into sharper pricing for every shop in it. The shops that join now aren’t customers; they’re the shops that built the index.
What members get
Free for life for the founding 100. Here’s the trade.
You send anonymous sale lines. Connected once, sent automatically — you never touch it. In return, the full engine.
The provenance line no other tool can print
Every comp shows why the number is right — including “N verified store sales.” Every tool you’ve ever paid for tracks eBay and the auction houses. So do we. The only sale no tool can see is the one that crosses your counter.

The shops that join now built the index
Members send anonymous sale lines — just the card, the price, the date — and the alliance turns real counter sales into sharper pricing for every shop in it. Founding shops aren’t customers; they’re the shops that built the index.
Every marketplace, plus the feed they all miss
Every major online marketplace plus the alliance’s verified store sales — weighted above eBay. Free for life on the data tier for the founding 100.
Signal weighting
Store sales carry the highest weight in the engine.
How the data moves
From your counter to the comp.
Your $40 sale lands in a pool next to dozens of online sales of the same card, with no origin of any kind. Your sale makes the number sharper for every shop in the alliance — and points at no one.
Your counter
Completed sale
Card · price · date. No other fields exist to send.
CompIQ ingest
Anonymization
Identity stripped at the door — no origin survives into the pool.
Identity resolution
Matched to the one canonical card it actually is.
Quarantine
Anomalies flagged and held out — a bad line never touches the number.
The comp
Blended aggregate
“14 verified store sales” — weighted above eBay, traceable to no one.
The data covenant
Six nevers, all structural
An alliance only works if no member can be used against another. Every promise below is structural, not a policy — not “we won’t,” but “the system can’t.”
Never your store name
Sales enter the pool with no origin attached; a comp can't be traced to a shop, even by us.
Never your customers
There is literally no field to send customer data; the API schema has no name, email, or address anywhere.
Never your costs or margins
Never collected — no field exists.
Never anything non-public
The feed is completed sales — beyond that, nothing you don't already show the world on your own site.
Never resold or shown with your identity
Only blended aggregates, ever.
Never used to compete against you
Collector Station's own sales enter the pool by the same anonymizing mechanism, under the same covenant.
Disconnect anytime — the feed stops immediately
Getting started
Three steps, five minutes.
Connect once — about 5 minutes
Shopify or Square: connect your store once and you're done. No exports, no uploads, nothing to remember. Everything else gets a one-time CSV while we build your connector.
90 days load automatically
The first sync backfills your last 90 days of sales on its own, then it just runs — background sync plus real-time.
Your dashboard lights up
Your inventory priced by the full engine, your sellers vs. the alliance's, and comps that carry the line no eBay-only tool can print: “N verified store sales.”
Proof
Built and battle-tested at Collector Station.
Already powering Collector Nation’s on-air pricing.
