Barcode scanner app?

[Mikaya]

Maybe your smartphone has an app which can scan any product to find the cheapest price for it? I think this is pretty neat. xD

I've had a go at some items, such as games and household products.

I never use Barcode scanner they are a bit lame and unnecessary so i just use Qr code sometimes to find my way to the product i buy but i am not gonna waste my time on those things
