Anybody knowledgeable about fairtrade chocolate ?

[OnChickWatch]

I'm wanting to do a chocolate tasting and I know that dairy milk and kit Kats are both fair trade but I need some more bars. I had a quick look in tesco last night but couldn't find any others. I'm really looking for things that would be recognisable to children.

Co-op and Sainsbury's have a great range.

Thank you will try there, don't usually shop in there.

I really am looking for 'named' things like creme eggs, crunchie, twix (none of which are fair trade I don't think)...
