Fun with Numbers- Cheaper soda- 12pack or 2 liter?

(Ad caption:  "How soon is too soon?  Not soon enough.  Laboratory tests over the last few years have proven that babies who start drinking soda during that early formative period have a much higher chance of gaining acceptance and 'fitting in' during those awkward pre-teen and teen years.  So do yourself a favor.  Do your child a favor.  Start them on a strict regimen of sodas and other sugary carbonated beverages right now for a lifetime of guaranteed happiness. -  The Soda Pop Board of America")

Ever go to the supermarket and wonder which is cheaper- the 12 pack of brand name cola on sale for $3.00 or simply to buy a 2 liter bottle at the regular price of $1.39?  Obviously if you buy one 2 liter bottle, it will be less expensive than a 12 pack, but let's delve into the numbers a little bit.

A 12 pack of cola is 144 fl. oz.  A 2 liter bottle is 67.62 fl. oz, making two bottles equal 125.24 fl oz of soda.

A 12 pack on sale for $3 comes to.0208cents per oz. A 2 liter bottle @ $1.39 comes to .0205cents per oz

In this example, the cost differential is 22cents less to buy two 2 liter bottles but overall, its not enough of a difference to bypass the convenience and portability of cans vs large bottles. Of course buying generic brands or not drinking soda would be even more economical but this blog is not about denying oneself every joy and pleasure in the world just to save a penny.  The goal is always to maximizing one's buying power while also maximizing the value and happiness that product or service brings.
