What has me whipping my phone calculator out in the grocery store? Answer - toilet paper. Since Brian's days at P&G, we've been a Charmin family and I don't really consider other brands. Which is good...... since Charmin does a fair job giving me choices all by itself.
First - extra strong or extra soft? (I exclude 'basic' from the get-go). Ok - is there some rule about toilet paper not being both strong and soft?? Also, if it's not basic - is it deluxe? We choose strong - it is moderately soft and who wants toilet paper that might fall apart? (actually, I can't tell a lick of different between soft and strong - so I defer to the former paper engineer.)
Second - do I want 12 mega rolls or 8 super rolls? Or 16 giant rolls? 16 giant rolls might be $14, while the 12 mega rolls are $9 and the 8 super rolls are $4. But the math is not that simple people - because 16 giant rolls is not twice as much toilet paper as 8 super rolls. Each super roll is 2 regular roll but 16 giant rolls is 4 regular rolls; and a mega roll is 3 regular rolls!
To determine the best deal on toilet paper I have to compare the prices per number of regular rolls. (what's the MOST funny is that toilet paper is the ONLY product in the store that I am consistantly worried about getting the best value for - there may be twice as much cereal for only $1 more and I think - "yeah, but I don't want that much").
P&G is nice enough to provide the regular roll conversion for you on the front of the package. None-the-less, I have to divide the prices by large numbers ($14/36 versus $9.52/24). I try to do the 24 is 2/3 of 36 so what is 2/3 of $14 and is that more than or less than $9? $9 + $4.5 is $13.50 which is a little less than $14, but when I factor in the $0.52 fudge factor it's too close!!
So yeah - I got out my calculator to ENSURE that I got the best deal on Charmin extra strong.
