Buying isk from a website has SIGNIFICANTLY higher risk, since the accounts and characters associated with those sites transfer large quantities of isk around on a daily basis, whereas sellers on this forum do it once or twice a year. Thanks for trying to set the "right" price in an open market.
EDIT: Furthermore it appears you yourself are willing to pay more than a 1:1 ratio
