This app is awesome for college students buying textbooks.

Using this app in the college bookstore has saved me at least $100 by finding the cheapest price for my books (and has saved me a few hours worth of time). I haven't used it on many other items yet, but I look forward to trying it on electronic gadgets, etc. I do wish my device's camera was compatible (I have an older Pearl), but as I noted the savings of time and money I have gotten are well worth typing in the barcode. Nice job.
