Kind of new to Deckbox but not new to trading. I try to send all packages in a double sleeve and top loader put into a bubble mailer. I also try to always get tracking for all trades I do so as to make it easier for the both of us. I also don't mind trading down up to $3.
I.E. I have something worth $10 and you have something worth $8. I'm mostly okay with trades like this as long as they are reasonable.

Enjoy playing combo and midrange decks. Feel free to ask me anything about trades. I will happily send pictures if you ask for them.

I use paypal for cash requests as well.

Let me know if there is something you are looking for in C/Un and I'll see if I have any.
