Series 8 hit the stores...
If you're in Poland check out your local Carrefour. I've been sent photographic proof that they are on the shelves now! (thanks Bart)
I'm also told they are available in Spain but I don't have any further details. If you do, please let us know. (thanks Indy4477)
UPDATE - we've also heard that they are available in Sweden & Portugal. Thanks to Indy4477 and Reekatdoo for the info. Anywhere else?
