Post it for the very least amount of what you are willing to sell it for.
If you are listing silly low in hopes of getting an instant sale at a high price chances are you will be sniped by lowball bids.
All items that drop I list for 1 and accept what comes. Sometimes I win and sometimes I lose. Usually I don't bother to check.
When I am flipping I run somewhere in the 60ish% range. Typically I get the market norm. Sometimes not.
Items that I have converted, which I have finally started to do, I list at the same 60ish%.
Works for me....hope it is of some help to you.
