@BuyersRemorsechu asks
shop offered one amount for everything but I only want to sell half now. Can I expect exactly half the offer?
Jeff answers
I'd ask for a new offer on the actual group you're selling. The desirable cards may account for much more than half of the value or interest. Use our app to understand the individual references, but don't assume a collection offer divides evenly by card count.
