They changed it.  That is so not fair … or is it? You can check out a video news story on the delicious shrinking Toblerone bar here.

Two sizes of Toblerone bars are now configured differently.  How much did they lop off? How much did the price per gram of chocolate change? Is the price per gram still the same, if not how might you adjust the price of the products to make it fair?  How much could you buy for $1.00?  Could you have designed it better?
