Don't know about NSC or LSC, but I did an experiment trying to stock the WHC market, after I saw this Flack Attack market post:
https://forum.eveuniversity.org/viewtop ... 6&t=113601My experiment was a horrible failure, but I learned a lot from it. I chose a doctrine and stocked everything from it on the market (heavy armor, in my case), from hulls to fittings. Very few things sold after about 4 to 5 months. Basically only drones, ammo, cap boosters. As I withdrew to try and get some liquid isk flowing again, I asked the members. They told me it would be better to put the ships up on contract fitted, rather than in pieces in the marketplace. Also, the "hangar firesale" forum posts and slack blasts seem to work very well and quickly. The firesale messages seem to work at NSC also (I have bought a few myself!).
Turlough said contracts, and I'll echo his sentiment. Each campus has favorite doctrines, find them and see which contracts are missing. In addition, check out the Flack Attack sheet, and see what kind of small consumable items the campus may need in the actual marketplace.
