Topps Bunt Question
 

I see people selling Bunt cards on ebay and have a few I would like to get rid of. How do you transfer the card to someone else after selling it? I know you can trade, but you can't send a card without selecting something in return.

Anyone know how this works?

from my experience you just offer them the trade with your card and white base, asking in return for the same white base card. it allows them to receive the card they bought without losing anything. So it's a 2-for-1 trade where two of the cards are the exact same card so that person doesn't lose out
