I haven't gotten any M&Ms in a while, but I feel like long ago there were two shades of brown and more recently only one. Also, whatever happened to blonde Oreos with chocolate filling? I know they existed once, but every time I'm the grocery store I check and they're not one of the dozens of flavors.
