Mais Vantagem

Have you been to a supermarket trying to decide between two products, making multiple accounts to find the best 'cost x benefit'?

What if you had an app that would make these accounts for you, and apart from the most advantageous product, would you report the percentage difference between them?

This app was created for this purpose!

Ex: 350ml coolant that costs $ 2.27 and a 250ml that costs $ 1.84?

Use the app and find out which one is more advantageous!
