In this link, it is said some companies sell halal certified crap without actually identifying it. Also not the other sign for halal certified stuff the crescent with the big M.
Otherwise, this appears to be a good link for clicking on whilst out and about to see if the company you are considering buying one of their products is sucking up to the moslem vermin. This one does it by product type and note there is a lot of dead air between bakery products and beverages. Don't let that fool you into thinking that's the end of the list.
Happy NON-halal Shopping my Neighbors !
