That is indeed very odd. Most people experienced better ratios after we removed the cookie-dependency on our linking codes.
We haven't used the linking codes from ccbill for over two years, I think its more likely that the sites you have the old codes on just get more productive traffic to them. Its almost impossible to see a pattern with so few sales.
Please contact
[email protected] or our affiliate manager Louisa over icq so she can see if she can help bring your ratios up, or see if there is a problem somewhere.
