Match the exact item
Search the full name, set, card number, sealed format, grade, retailer tag, or promo wording before comparing price. A broad Charizard or ETB comp can be the wrong market.
Use this workflow before buying from a showcase, selling into a shop, or agreeing to a trade on a convention floor.
Table-side workflow
Do these four things before the conversation turns into a negotiation.
Search the full name, set, card number, sealed format, grade, retailer tag, or promo wording before comparing price. A broad Charizard or ETB comp can be the wrong market.
Completed sales show where buyers actually cleared. Use them before letting a seller ask, sticker price, or showcase label become the anchor.
Active listings show current supply. If a shop price is above the active floor, the item needs a reason: cleaner condition, no shipping risk, local convenience, or stronger evidence.
For buying, set a max price. For selling, account for dealer margin. For trading, compare both sides after condition and liquidity are clear.
Buy, sell, trade
A collector buying for a personal collection, a dealer making a cash offer, and two people balancing a trade all need different checks.
A fair buy is usually near buyer-confirmed value after adjusting for condition, taxes, and the convenience of getting the item in hand. Be stricter when the item has weak sold comps or many active listings below the sticker.
A shop needs margin, so cash offers below CollectAIO Value can still be rational. Compare the offer against what you would net after fees, shipping, time, return risk, and possible price movement.
Do not compare sticker totals only. Use the Trade Analyzer when one side has sealed product, graded cards, raw cards, or cash because liquidity and confidence can be uneven.

FAQ
These answers keep the guide grounded when the negotiation is moving quickly.
A fair card shop price is one that lines up with recent buyer-confirmed evidence after condition, taxes, fees, convenience, and dealer margin are considered. It does not have to be the lowest online ask, but it should be explainable from real market evidence.
Start with sold comps because they show completed buyer behavior. Then check active listings to understand current supply and whether a lower comparable item is available right now.
Decide your max price before negotiating. If the quoted number is above sold evidence, above active supply, or requires ignoring condition problems, walk away or add the item to a watchlist.
Value both sides from the same evidence type and adjust for liquidity. Cash, sealed product, raw cards, graded cards, and thin-market promos should not be treated as equally liquid just because the sticker totals match.
