Happy Valentine's Day to you, Eleanor.
Those Cadbury chocolates look delicious! I've only seen the Cadbury bars (hmm, with raisins and nuts). I've never seen Cadbury boxed chocolates.
They do several different types of boxed chocolates plus chocolate and toffee selection which are supplied in cartons or at Christmas and Easter in large tins, these are called Roses.
One of the boxed chocolate selections I referred to is also a speciality Roses ones.
In addition to that there are well over 20 different type of chocolate bars they do
Here is a link to a few of them - it is quite fun to explore this website as well - makes one hungry
