My twin sister has coeliac disease which means she can't have normal wheat or gluten foods. Only fairly recently (past 3 or 4 years) have ASDA, Tesco and a few others started labelling their own products properly for this.
Now, some places have their own special shelf for gluten-free food, which is usually along side the organic stuff.
I'm sure they can find a place for the dairy-free stuff.
