I'm almost exclusively a casual player and the love the game for that aspect.  EDH and its variants are really my focus, so carrying multiple copies of cards is not really my goal. Almost everything in my inventory is tradeable, it just has to be for the right thing...I tend to grade verbatim to TCGplayers condition guidelines.  Any exceptions to that I strive to bring up in the trade.  We all make the occasional mistake and I am no exception.   
At a minimum I send with tracking due to my local post office's talent for losing untracked mail.  So to justify the tracking cost I try to trade in significant values to offset them.
Please be patient with communications, sometimes my work/life schedule is very intense.  Happy trading!
FYI: If you don't have much deckbox trade cred, or a few bad reviews, I'm probably going to ask you to send first (to me this amounts to common trade courtesy).
Sealed product I have for trade/sale:
- Commander: Counterpunch
- All Commander 2013 Decks
- Duel Decks: Izzet vs Golgari (Japanese), Zendikar vs Eldrazi
