CheaperChecker

Use CheaperChecker to quickly compare prices of items sold in differing quantities to see if buying in bulk is really a better deal, or to compare different brands of items.

For example:

There are 2 different brands of instant oatmeal.
Brand A comes in boxes of 12 packets that weigh 0.98 oz for $4.00
Brand B comes in boxes of 10 packets that weight 1.51 oz for $3.69

Which is a better deal? How much better is it?

Plugging in the numbers to CheaperChecker shows that Brand A costs 39% more per oz than Brand B, so if you eat oatmeal every morning before work you could save almost $40 a year by eating Brand B instead of Brand A!
(Assuming you eat the same amount of Brand A vs Brand B every morning)

CheaperChecker can also compare items in different scales, like lbs to kg or liters to fluid ounces, making it easy to compare 2 liters of soda to a 12 pack of cans, or import items compared to domestic.
