How long do you think packaged candy would last? I am thinking of getting the Halloween clearance candy for OOT bags and favors. My wedding's on April 10, the week after Easter, so I suppose it'd be better to just wait for Easter clearance candy. But the Halloween M&Ms contain green and black candies (our colors) and that would be cool for favors I think. Would they last until April if kept in a cool dark place?
