About CostCast Custom Unit Price Converter

This extension is made to limit impulse buying. It is so easy to shop and buy items without even looking at the prices, and it can get a bit out of hand. This app is made to counteract this, to try to make people double take at the prices, and put it in a perspective they can actually understand. Set your item and cost, and watch all the prices shift into sodas, or anything you can think of. Have fun while shopping and set the units to personalize what works for you.
