put your junk in trades (10 items each trade) and in wish list type this "perfect for packrat avatar bid fairly please" and whatch as people bid away
I set up 3 trades of 10 items here is what it was like
#1 items value - 200-300 , Bid was - 800
#2 items value - 200-300 , Bid was - 800
#3 items value - 400-500 , Bid was - 1000
so as you can see you make quite a bit of profit this way!
I had all those bids in about 2 mins from putting them up
Hope this helps
