Just another quick example of 1 days worth of buying on one character from more or less passive buys orders (orders I update very infrequently and mostly just let sit there until they get filled) on one of the main trade hubs.
The carrier and capital ship book purchases are particularly nice with anywhere from 40 million to 125 million ISK profit per book if I were to resell them at school prices. Of course that's not including taxes and fees which come out to approximately 10 million per book but then again I'll be reselling each book for at least 10 million and maybe as much as 50 million over the school price.
I should wind up with at least 400 million profit on just the carrier and capital books.
Though the buy orders had 10 jump range all of the carrier and capital books were sold to me directly on the hub so I didn't even have to transport them to the hub. In fact they were all sold to me by the same player and completely filled my buy orders for all 3 books. Maybe I should start buying 5 or 10 at a time instead of 2 or 4.
