I don't think it's a UK thing actually. I'm pretty certain the website I found it on was from the US as they talked about Girl Scout cookies too. I came across it purely by accident several months ago but I marked it on my calendar to make sure I didn't miss it!! I reckon it's International so I say join in @apple, and toetapping,!! I'll happily jump on any bandwagon that gives me an excuse to eat chocolate of any kind but I am somewhat addicted to chocolate raisins!
