To negotiate trading card prices at a card show, scan the card with a phone app that pulls recent sold comps, then anchor your offer to the median sold price minus a condition or bundle discount. MaxBid AI returns sold comps and a personal max bid from a photo in under 10 seconds, which fits the typical 60-second show-floor negotiation window.
The MaxBid AI offer formula at a card show: Offer = recent sold comp median, minus condition adjustment, minus a cash-or-bundle discount, minus your required margin.
Pull the recent sold comp median for the exact variant and grade, subtract a condition adjustment for any visible wear, then subtract a cash or bundle discount. Anchor your offer to that number, not the dealer's asking price.
Use a scanner app. MaxBid AI accepts a phone photo and returns sold comps plus a personal max bid in under 10 seconds, so you can answer a dealer inside the typical 60-second negotiation window.
Roughly 80 to 95 percent of the recent sold comp median, adjusted down further for any condition issues or if you're buying multiple cards from the same dealer. Bundling earns a real discount, ask for it.
