Don't bother selling exotech stims, they usually selll for less than the mats even when accounting for crits.
Depending on your server, this is not true at all. I made about 1.5 million last week on them. Granted that's an extreme amount since I had built up a good amount of radioactive paste inventory, but still, saying "don't bother" isn't always the rule. I make a lot of profit on them.
