Like the webpage, the Buscapé app is a great alternative to help you find the best price before making a purchase.
Functions:
To find the best price and make the purchase directly from the device, it provides a barcode reader, advanced search filters and shows deals on the map.
How to use:
You need to make a unified registration (Buscapé and Bcash). Purchases can be made only in Brazilian stores and you get back 5% of the purchase price in the form of credit.
