This app has no product info at all actually. It is just sending you to info from Google product search, and Amazon.
Google *web search* has it...
But Google product search doesn't...
Amazon doesn't... or has this number by coincidence in something to do with a typewriter:
http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=078354703328
You know it's cheese because you're holding it, so you'd know it was a bogus hit from Amazon. I'd tell Amazon, if anyone.
The right answer is 'no results' -- stuff like cheese isn't usually sold online, in comparison to DVDs and books.
You should think of this app as just a scanner for QR codes and the like with a bit of info on the side for convenience. Use Shopper or something else for purpose-built comparison shopping.
