You guys seem to know a lot about trading, so I wondered, what's a good way to sell odd-level items? (I have a trade on outpost, /trade/10274980/ )

Hmm, I haven’t spoken to the other mod just yet and he might have a bit of wisdom but I personally have had pitiful luck both buying and selling off-leveled items (don’t recall ever selling one - buying got me a lot of OH HE’S NEW HE MUST BE WILLING TO PAY THAT MUCH FOR A NORMAL WEAPON spam from people who didn’t read the notes).

I think the best bet is probably list them everywhere you can, keep the trades bumped and hope a person who wants one comes along.

Also it might be worth having a flick through the search every now and then to see if anyone is looking to buy one. For a Dead Ringer, you might have a little luck.
