(Err I can't change the title so ignore it...)
Normally I will sell ISK with US$4 per 1B for new customers and small amounts, but I can offer as low as US$3.3 per 1B for large amount buyer (at least 100B).
My only requirement is that you must pay first in PayPal (with Purchase Protection). Yeah I know this protection is weak, but weak protection is still better than no protection...
Contact me via PM, E-Mail or Discord, never discuss in in-game chat, you know...
