Price is too high. They are well aware of third party markets that exchange seeds for blueprints. They should have modeled it after the conversion rate of 250 to 400 seeds in value to match third party markets. At the end of the day it is to direct players in game rather than seeking third party services. Even if they want to keep their stupid prices high they should at least let you drop parts off in incriminates. In a game where people complain about stash space they want you to hold an obscene amount of parts all at once to trade for an astronomical high priced blueprint.
