Haven't been on the forums for like a week or two and I come back to a ton of threads discussing card-trading? Can someone explain to me how we do this? Thanks ^^
Since they're physical items, you would have to mail the card you're trading to the other person and they'd have to mail a card to you. You could just exchange addresses through PMs.
I have bought some cards here as well. I just sent them money over paypal. But I have traded 1:1 with several people so both seem like good options to me. Just make sure you can trust each other, if you have doubts, ask them to write their name on some paper and place the cards on it and take a pic.
