Well I spotted these in Sainsburys this morning, so having bought a few bags there walked into town - found the new boxes in a local toy emporium, luckily they said it was ok to buy a sealed box (hurray!)
So, out of a box of 59, I got two full sets (just short one surfer girl)... the artist, scientist and footballers seems to be really very common, I have enough sailors to man a small cruiser, and (in my experience) the musketeers, female ice dancers, viking chaps and gnomes I only got three of. SO I'm really quite pleased, having not got a box of series 3 but spent ages squinting at silly hard to see dots in the stores...
As well as on here there is a nice guide to figures here along with a dot decoder - I have to say that I found reading the dots on the orange packages far more difficult than the green ones of series 3...
