These are my favorite as well, though (and we may have already discussed this on this forum) but they have shrunken significantly over the last 10 to 15 years, with generally no decrease in price.
I don't really care for them, but they are my wife's absolute favorite. Not only have they gotten smaller, they moved to this new plastic container that isn't an improvement over the old foil one.
And they've made all sorts of other varieties. Like the Caramilk one.
