It's not as simple as the ad above, posted by Bits and Pieces, via Miss Cellania.
Here's an example from our local grocery store last week. Assuming that the quality of the products are otherwise equivalent, which of the following two lots of toilet paper offer the better bargain?
a) 24 rolls (200 sheets per roll) for $12.99
b) 9 rolls (385 sheets per roll) for $7.28
Obviously any sixth grader with a calculator can solve the problem. But try doing it in your head in a reasonable time before people wonder why you're staring at TP packages.
Then decide whether you should buy your Early Times bourbon in the 1 liter size for $12.99, or in the 1.75 liter size for $19.99, factoring in that you get a $10 rebate for the purchase of three of the 1 liter bottles.
