Hi

If you add the line after:

Code:
 if ($instock) {
        $query_Where = " and p.products_quantity>0 " . $query_Where;
    }
e.g.

Code:
 if ($instock) {
        $query_Where = " and p.products_quantity>0 " . $query_Where;
    } 

 $query_Where .= " AND p.master_categories_id != 350 ";
it should then make sure that no products from this category are included any of the data feeds.
