You are the consumer and as such it is up to you to determine the unit cost of a product before purchasing.

"Special Value" doesn't always mean that a savings is involved any more than purchasing the large size of an item means better savings.

Use your calculator and figure out exactly what you are getting for your money before going through the checkout. No one is going to do this for you, if you want the most economical bargain then you need to figure out exactly that that is.
