I'm not quite that bad, but I definitely overcharge for some low-level droid parts. A big part of the problem is that the way GTN works makes it hard to have a good market. You can't tell where supply or demand is at, and it is a pain to keep stock stuff that often doesn't sell. I overcharge as a premium for the trouble, and I don't feel bad about it. But I do wish that GTN was better. Maybe if people buying could put out requests for bids, in addition to the selling side they already have.
