Subject: Re: OT: Hershey
A bit of napkin math. Google tells me that the Hershey chocolate bar is 43g (1.55 oz) and is 11% cocoa.

If cocoa is EUR 9600 per metric ton (as per the article) that's enough for 211,416 chocolate bars or about 4.5 euro cents per bar.

I'm sure there's some poor assumptions there but as a ballpark calculation it doesn't look like it's too bad for the maker of low quality chocolate (11% compared with 20% for the average bar, according to the article).
