Well, it would appear that Cadbury's has discontinued the Truffle Egg, and Dream Egg. I don't know whether they were exclusive to Canada or not, as Cadbury's products are different in Canada and Europe. Nonetheless, I've been looking for these two (they were never easy to come by, but I think they're actually gone, now), and have found the stores carrying the traditional Cream Egg, Caramilk Egg, Maple Caramilk Egg, Wunderbar Egg, and Peanut Butter Egg (which is repulsive).
As well, I think that Milka's has dropped the chocolate variant of their L'il Scoops egg. They've been packaged in fours for as long as I've been eating them: two chocolate cream, and two white cream. Now they come with four white cream eggs in a package.
Needless to say, this won't be as happy an Easter as others!
