When looking at google, it appeared that http://www.uk.cj.com/ was an off-shoot of cj with offers specific to the uk, but when i try to sign up it just takes me to cj.com which i am already a member of. Can someone explain if there is a difference. Thanks
There is no difference AFAIK. Only for merchants, they deal with the UK office. Publisher wise you just pick the £ offers from all the aff deals in the log in.
