Doctor Archive

Hi all. My main is a master doc and I just made an alt who is going to be a merch. My question is, how well do advanced subcomponets sell from vendors and what should the mark up be? Do all of you make your own subcomponets or do you sometimes buy from other docs?

On Eclipse I find they don't sell, really at all. Occassionally I'll share a crate with a doctor but I've tried selling them to no avail. Don't know if its like that on every server.
