I've been playing (again) since Shadowmoor, and stayed with Commander and draft for years, but am getting ready to dip my toes into Standard.  I have tons of Commander playables, looking to acquire standard playables, especially fetches.

I check my trades daily, and once a trade is confirmed, I pack it and add tracking immediately, and it is in the mailbox that night to go out the next day.

If you propose a trade that has a disparity of $1.00 or more on either side, I'd like an explanation so I can understand where you're coming from. 

I always check my cards for condition and let you know if it's not really as advertised.  I would hope that you do the same.   

Here's how I send unless requested.
$. - $20.    Standard envelope
                  w/ top loader
                .
$21 - $.      Top loader in a bubble
                  mailer with tracking.

I look forward to trading with you!
