Is that the chocolate with the sugary crunchy minty or orange bits in it? I'm an ex-pat Brit living in Cloverdale and there is a British store in Langley I go to to when I miss Battenberg, Bournville chocolate and Fox's glacier mints too much. They might have it there as they have a good selection of British sweets and chocolate. I could have a look and bring some too and at least you'll know there is somewhere you can get that chocolate in Vancouver.
