Unit price checking- Which "deal" would you pick?

Last week, family movie night called for a little something for the sweet tooth.  Remember what I discussed about saving money on food and checking unit pricing?  Here is a prime example.  I didn't have to go all over the store to find like items.  These were all on the same aisle within ten feet of each other.  The images are a little fuzzy so I will include the unit pricing above each photo:

This is your basic two cup size pack or 1.5 oz with a unit price of .66 per ounce.  

 This has a smaller size cup but is $1.39 for 4.4 ounces or about .32 an ounce.

This is the equivalent of the first photo times six with a unit price of .55 an ounce.

The point I want to make is that these unit prices are ALREADY LISTED ON THE TAG.  No calculator is needed.  It does get tricky on other items that may list it per piece, per pound, per gram, etc where you can't easily compare apples to apples.  At that point you will need a calculator.  So, back to our peanut butter cups.  In this example, thinking only of money, you can spend .99, $1.39, or $4.99.  The latter is a significant difference in price above the others but not the best deal.  If you buy the pb cups for $1.39, you are saving quite a bit and essentially getting twice the amount of candy for the same unit pricing as our first example.  We bought the $1.39 Reese's cups.  Which would you buy?

There you have it.  A small savings on Reese's PB Cups that by using this example can extend your savings on everything you buy at the store! Enjoy.
