Also seen (and bought) in the 99p shop today:
Swiss Delice Rive de Coco (white chocolate with refreshing coconut rasps) - specially for Smurfy - 2 x 100g bars for 99p. Surprisingly nice but predictably a bit on the sickly side.
Cote d'Or Lait, 3 x 100g bars for 99p but personally I found this disappointing.
