There is currently a 20% discount on MCT packs in the NES. If you buy the 2 year pack, that brings the monthly training cost from 192 to 154 PLEX. That by itself would bring down the price of injectors produced by those characters by around 45 million ISK.
The question is, how likely is that to be reflected in the actual price of injectors on the market? Are the suppliers going to depress the price, or more likely, just going to pocket the profit?
