We've all been there - Standing gob smacked in the shopping aisle holding a small jar of pickles in one hand and a very large jar of pickles in the other.

Now you know you want pickles. Lots of pickles. But you don't want to pay more than you have to. Should you buy lots of the little jar? Or just one of the big jar?

Of course, the only way to find out is to use Compare It, an iPhone/iPod Touch tool that quickly tells you where a bargain is and if it's a good one.

Just enter the price and quantity of the two items and let the tool do the rest.

This tool works with both metric and imperial units, and can compare all manner of things!
