@HoloAndBroke asks
I offered ten cards that add up to the same value as one card and the person wasn't interested. Isn't equal value a fair trade?
Jeff answers
It can be fair on paper and still not be a trade the other person wants. Ten cards mean more sorting, space, and possibly ten separate sales. I'd compare values in our app, then ask what they actually collect before building an offer. Nobody has to accept an equal total. Sometimes the missing ingredient isn't money; it's a card they're excited to take home.
