WHERE can i buy BN biscuits in the uk?

look. rememeber> they were those awsome little things like mid to late 90's like a sandwich of biscuit with chocolate or strawberry sauce stuff in the middle? and they had little faces cut into the front of them. i found some on Ebay but they would be crumbs by the time they arrived... please help me! best answers for people who give me places near newport in wales (will go to cardiff)
