My entire inventory is on my tradelist, since I really am interested in trading anything and everything if the price is right.  But there are a few caveats about the expensive stuff:

1) I am not interested in trading reserved list stuff for non-reserved list stuff unless the trade is clearly in my favor.

2) I am not going to trade my eternal staples for piles of bulk, even if it is favorable on paper.

Besides that:

1) I default to TCGplayer mid to price most cards.

2) It's not worth time or postage to make small trades less than $15 or so, so please don't start trades like that.

3) I only want Near Mint, non-foil, English cards, and I will not trade for anything else.

4) If you do not have anything on my wishlist, it is unlikely I will want to make a trade.

5) Due to high shipping costs and long turnaround times, I will not trade outside the lower 48 states of the USA.

6) 15 or less feedback sends first.  Otherwise, my preference is to simultaneously send.
