Moneybookers is not free, they will charge you as a merchant at least 1,9%
just take a look at their merchant fees

They are still mutch cheaper and they do even charge a lower rate for currency conversion than paypal. Paypal takes 2,5%, Moneybookers only 1,75%.
But Moneybookers seem to hold a chargeback protection on 6,9% - 7,9 %!?
I did not read all their t+c, but the fee table is at least showing something like this!
