Just got an Email from Haagen-Daz regarding a carton size change - they're downsizing "by a couple of spoonfuls" - 16 oz. to 14 oz. in late January, and 32 to 28 oz. in March 2009. (4 oz. is a bit more than a "couple of spoonfuls, however!)
I guess various uproars on consumers' parts perhaps encouraged them to preempt the same type of fuss on their packaging change. Not a bad decision on their part, IMO.
