The Toilet Paper Principal

I always shop with unit prices in mind but I still usually end up standing in front of the toilet paper doing math in my head (not a good idea, haha) trying to determine if a sale is actually a good deal. A Deal Seeking Mom reader came up with a simple and quick way to figure the price per square foot which will help you determine if the sale price makes the toilet paper worth buying.

Thank you, Deal Seeking Mom!!
