Hey @linguistics
I'm gonna need a Gricean analysis of these two grocery store maths.
I think that the implicatures are that (a) happy egg organic free range eggs should be conceptualized as individuals, while happy egg heritage breed eggs should be conceptualized as a group (flouting maxim of manner at least once) and (b) USian shoppers are likely to be too dumb to be able to calculate that 15 is 3 more than 12 (flouting maxim of quantity)?
