Cross-posting network

List once.
Sell everywhere.
Never undersell.

Your inventory should be working on every marketplace at once. 3 channels live today, plus 3 more in official-API partnership — all included with Pro Seller Ultimate.

We only list channels we can publish to through an official API. Anything not marked Live is not billable today — you are paying for the channels that are live plus locked-in access to the rest. As each partnership goes live, every Pro Seller Ultimate member gets it at no extra cost — your rate is locked to the stage you joined on.

How cross-posting works.

One scan, every storefront
Scan a card into your vault and publish it to every connected marketplace in one tap — or in bulk, up to 1,000 cards at a time.
Fees and net proceeds up front
See the estimated marketplace fee, Rookie seller fee, and what actually lands in your pocket on each channel before you list.
Never oversell
When a card sells anywhere, Rookie pulls the listing down everywhere else automatically — no double sales, no angry buyers, no manual cleanup.
Priced by evidence, not guesswork
Every listing is anchored to live sold comps, PriceCharting, COMC, and Rookie's own sale history — with a shareable comp report that justifies your ask.

Sell-everywhere stage pricing

  1. Stage 1 — LaunchYou are here
    $99.99/yr
    Rookie + eBay + Shopify live

    Where we are today. Cross-post, bulk list, and auto-sync sales across Rookie, eBay, and your own Shopify store at the 3% Ultimate seller fee.

  2. Stage 2 — Expansion
    $149/yr
    4+ channels live

    Takes effect for new members once a fourth channel (Whatnot is next in line) is publishing through its official API. Anyone who joined in Stage 1 keeps Stage 1 pricing.

  3. Stage 3 — Full network
    Announced at launch
    Every partner channel live

    The complete list-once-sell-everywhere network. Again: your rate is locked to the stage you joined on, for as long as your membership stays active.

Pro Seller Ultimate is priced in stages: the more marketplaces we light up, the higher the annual price for new members. Join at today's stage and your rate is locked for as long as your membership stays active — every new channel is added at no extra cost.

We only list channels we can publish to through an official API. Anything not marked Live is not billable today — you are paying for the channels that are live plus locked-in access to the rest.

Built for the whole hobby

One collector or ten thousand cards.

The same pricing intelligence, cross-posting, and protections whether you own three cards or three showcases.

Collectors

Know what you're holding.

Daily re-pricing on your whole vault, buy/sell/hold guidance with a fair-value range, and alerts when a card crosses your target.

Sellers & flippers

More eyeballs per card.

The same card working on Rookie, eBay, your own Shopify store, and every channel we light up next — with net-proceeds math per channel so you list where you make the most.

Card shops & dealers

Move inventory, not spreadsheets.

Bulk cross-list up to 1,000 cards at a time, auto-list new intake by rule, and let sold-sync retire listings across channels.

Breakers & consignors

Prove the price.

Shareable, comp-backed value reports for every card — ordered most-similar-first — so buyers see why a card is worth the ask.

Cross-posting lives in the app.

Connect your channels and publish from the Rookie app. Memberships are purchased in-app under Settings → Membership.

Pro Seller $59.99 a year (Rookie marketplace, 5% seller fee) · Pro Seller Ultimate $99.99 a year (cross-sell to every live partner channel, 3% seller fee). Annual memberships only — no month-to-month plan.
