Price Cruncher

Are you trying to get on top of your expenses? Find it difficult to compare prices at the grocery store while on the go? Is it cheaper to buy 152 diapers for $35 or 72 diapers on sale for $19. 95? Is that 20kg package of dog food from Costco really a good deal compared to the 2kg bag at the Walmart? How much are you paying for each sheet in a paper towel roll?
