You want profits from trading, right?
Earlier on I saw a fellow jammer with a sled. I quickly chose a worn blanket to trade for their sled. I thought this was a good trade for me because a, worn blankets were from the Lucky Party not long ago and b, I had two of them, didn't need an extra one and I didn't think they were worth much. Anyway, I needed to choose something, right? So I traded my worn for the sled. Whaddya know? She/he accepted my trade! My mind was going, “Hooray!” :) I got a rare item! Then I happened to come across the furniture shop in Jamaa and looked at the latest furniture. You know what I saw? The sled I just traded for! Oh no! I was ripped off hugely. Now, every time I trade, I check all the stores first, to see if they sell the same, common items in jammers' trades.
