My friend found something in warmhole, how much does it cost to sell

the isk in the est isk amount it’s close to how much it sell in jita

i am asking because someone is want to buy for 1000 isk, and in market it cost ~49 mil, if i am not wrong. So i thought maybe it`s cheaper. But not 1000 isk, i understand that

that “someone” it’s a scammer, you can either sell the item in jita or one of the other trade hub or turn it into a t3c subsystem

however, it’s has a chance to not give you the subsystem
