When you go to the store to buy something most items will come in different sizes. For instances a box of serial will come in a 750 gram size priced @ $4.95. Then in big letters it will say "Club Size" 1.5 kg @ $10.01.

One would expect that there is a saving when purchasing the club size and in most cases there is, but not always!

Or how about a case of beer! The price of a 24 pack is $24,95, a 36 pack $37.95. Which is the better deal?
