I really like this app as well. You scan any barcode. For example, take your favorite face scrub and scan the barcode. This app will search for the best deal out there. How cool is that? Plus, you can use this app anywhere. I like to use it before I leave the house, but if I find an item that Iā€™m debating on buying in the store, this app comes in handy with comparing prices.
